Product Overview

The Schneider Electric TSXASZ200 is a two-channel analog output module designed for the Modicon TSX Micro automation platform. It converts digital control values from a compatible PLC system into analog electrical signals used to regulate industrial equipment, including variable frequency drives, control valves, and other process-control devices.

Analog output modules are essential in automation systems where equipment must respond to continuously adjustable commands rather than simple ON/OFF signals. For example, a PLC may calculate a required motor speed, valve position, or process setpoint and send the corresponding digital value to the output module. The module converts that value into a standardized analog signal for the receiving device.

The TSXASZ200 supports current outputs of 0–20 mA and 4–20 mA, as well as voltage outputs of ±10 V. This flexibility allows it to support different types of industrial control interfaces, provided that the receiving equipment is compatible with the selected signal range and electrical characteristics.

With two independent analog output channels, the module can provide command signals to two compatible devices or control points. Typical applications include motor-speed references, proportional valve commands, process setpoint transmission, and other applications requiring PLC-generated analog signals.

The module belongs to the legacy Modicon TSX Micro family. Schneider Electric lists the TSXASZ200 as discontinued, with no direct replacement specified. It may therefore be relevant to maintenance teams that need to keep existing TSX Micro installations operating or source compatible spare parts for established machinery.

Before purchasing or installing this module, users should verify the complete catalog number, PLC compatibility, output type, wiring arrangement, and software configuration. Similar-looking analog modules may support different signal types or belong to different PLC platforms.

Technical Specifications

Note: The dimensions and weight above are the supplied listing values. Confirm the exact hardware revision, terminal arrangement, and physical measurements before installation or shipment. The manufacturer’s published product data lists a net weight of approximately 0.2 kg.

Function and Working Principle

The primary function of the TSXASZ200 is to convert PLC-generated digital values into analog signals that external equipment can use as control references.

1. Digital-to-Analog Conversion

The PLC calculates a control value based on its program, sensor inputs, operator commands, and process requirements. The output module converts the programmed value into an analog electrical output.

For example, a PLC may determine that a motor should operate at a particular percentage of its available speed range. The TSXASZ200 can produce a corresponding analog reference signal, provided that the drive is configured to accept the selected output type.

The receiving equipment interprets the signal according to its own configuration. Correct scaling must therefore be established in both the PLC program and the controlled device.

2. Current Signal Output

The module supports 0–20 mA and 4–20 mA current signals. These ranges are widely used in industrial control because they can represent process values over a defined range.

A 4–20 mA signal commonly uses 4 mA as the lower end of the measurement or command range and 20 mA as the upper end. The 4 mA starting point can also help distinguish a valid low-end signal from certain wiring or signal-loss conditions, although the actual fault-detection method depends on the receiving device and system design.

The module’s output load and wiring requirements must be checked against the manufacturer’s documentation before connecting field equipment.

3. Voltage Signal Output

The TSXASZ200 also supports a bipolar ±10 V output range. This allows the module to provide positive or negative analog control values to compatible equipment.

Voltage references may be used by drives, controllers, and other industrial devices that accept bipolar analog commands. The permitted input range, input impedance, signal common, and grounding arrangement should be confirmed before connecting the module.

4. Independent Output Channels

Two output channels allow a compatible controller to issue separate analog commands to two devices or control points. For example, one channel may regulate a motor-speed reference while the other adjusts a proportional valve.

The actual independence, channel configuration, and signal assignment must be implemented according to the module’s documentation and the PLC program.

5. Signal Protection and Isolation

The manufacturer’s specifications identify open-circuit protection for current outputs and an isolation voltage of 1500 V AC. These characteristics contribute to the module’s electrical interface design.

Isolation ratings must not be interpreted as permission to disregard grounding, wiring, or installation rules. Correct system design remains necessary to protect the controller, module, connected equipment, and maintenance personnel.

Role in Industrial Control Systems

The TSXASZ200 serves as the analog command interface between a compatible Modicon TSX Micro PLC and external control equipment. It does not independently determine process requirements; instead, it converts control values generated by the PLC into electrical signals.

PLC-Based Process Control

The PLC executes the control logic and determines the required output based on programmed conditions. The TSXASZ200 translates the applicable digital value into the configured analog signal.

This arrangement allows the controller to regulate equipment continuously rather than relying solely on discrete switching outputs.

Variable Frequency Drive Control

A compatible variable frequency drive may accept a current or voltage reference to determine motor speed. The PLC can calculate the desired speed, and the analog output module can transmit the corresponding reference.

The drive’s input type, signal scaling, minimum and maximum values, and control-source settings must match the PLC output configuration.

Valve and Actuator Control

Proportional valves and compatible actuators may use analog command signals to regulate flow, pressure, position, or another process variable. The TSXASZ200 can provide these commands when the field device accepts the selected output range.

The module does not directly guarantee valve positioning accuracy. Final performance depends on the actuator, mechanical system, feedback arrangements, control logic, and calibration.

Process Setpoint Transmission

In industrial process systems, a PLC may send a setpoint to another controller or device through an analog interface. The TSXASZ200 can support such arrangements where the receiving equipment has a compatible input.

Engineers should document the signal range and engineering units so that a value such as 50% corresponds to the intended process condition.

Industrial Applications

1. Motor Speed References

A compatible drive can use an analog reference from the TSXASZ200 to adjust the speed of a motor-driven machine. This can be useful in conveyors, mixers, pumps, and auxiliary equipment where operating speed must change with process demand.

The drive input must be configured for the selected current or voltage range, and the PLC scaling must match the drive’s intended speed range.

2. Proportional Valve Control

Industrial systems may require adjustable valve openings to regulate fluid flow or pressure. Where a proportional valve controller accepts 4–20 mA, 0–20 mA, or ±10 V, the module may provide the required command signal.

Valve feedback and closed-loop regulation require suitable sensors and control logic; an analog output module alone does not provide a complete feedback-control system.

3. Process Equipment Setpoints

The module can transmit analog setpoints to compatible controllers, such as temperature, pressure, or flow-control equipment. This allows a PLC to coordinate several process stages using programmed operating values.

The process variable, signal range, and receiving device’s engineering-unit scaling must be defined carefully.

4. Packaging and Material Handling

Some packaging and material-handling machines use analog commands for speed references, tension control, or auxiliary motion. The module may be used in an existing TSX Micro installation where its output characteristics match the connected equipment.

Where an application requires high-speed motion control, precise positioning, or specialized closed-loop performance, the module’s suitability must be evaluated against the complete system requirements.

5. Legacy Machine Automation

The TSXASZ200 is particularly relevant to maintenance of legacy Modicon TSX Micro systems. Keeping the original controller and compatible I/O hardware may reduce the amount of immediate modification required for an existing machine.

However, spare-part availability and the long-term support status of the platform should be considered when planning maintenance budgets and future modernization.

Installation and System Integration

Correct integration is essential for reliable analog signal transmission and predictable process behavior.

1. Verify PLC Compatibility

Before installation, confirm that the host controller and rack or expansion arrangement support the TSXASZ200. Check the applicable TSX Micro hardware documentation and the PLC configuration software.

Do not assume that the module can be installed in a different Modicon family simply because the product is manufactured by Schneider Electric.

2. Select the Correct Signal Type

Determine whether the receiving device requires 0–20 mA, 4–20 mA, or ±10 V. Confirm the module configuration and wiring instructions for the chosen range.

Using the wrong signal type may cause inaccurate control, unexpected device behavior, or possible equipment damage.

3. Configure PLC Scaling

The PLC program must convert the desired process value into the numerical range expected by the module. The analog signal must then be interpreted correctly by the receiving equipment.

For instance, a 4–20 mA output may be scaled so that 4 mA represents the minimum command and 20 mA represents the maximum command. The exact engineering-unit mapping depends on the application.

4. Check Wiring and Grounding

Use the specified terminals and wiring arrangement. Follow the manufacturer’s requirements for conductor selection, shielding, grounding, and separation from power wiring.

Analog signals can be affected by electrical noise, grounding differences, and wiring errors. Proper installation practices help maintain signal stability.

5. Verify the Load

The module’s specified output-load conditions must be respected. Check the input impedance or load characteristics of the receiving device and the total resistance of the signal circuit.

The manufacturer’s stated current and voltage output load specifications should be interpreted using the official wiring and technical documentation for the exact module.

6. Commission and Test

After installation, verify each output channel independently. Confirm the selected signal range, PLC scaling, receiving-device response, and behavior at representative low, middle, and high command values.

Where the process permits, test loss-of-signal handling and relevant interlocks. Document the final configuration so that future maintenance personnel can reproduce the intended operation.

Compatible System Components

The TSXASZ200 must be used with compatible TSX Micro hardware and appropriately configured field devices.

These are examples of components used in a complete automation installation. They are not necessarily supplied with the TSXASZ200 module.

Alternative Models and Replacement Considerations

Schneider Electric lists the TSXASZ200 as discontinued and states that it has no direct replacement. Any alternative should therefore be selected through a compatibility assessment rather than assuming that another analog output module can be substituted without changes.

Before selecting an alternative, compare:

• Number of output channels.
• Current and voltage output ranges.
• Conversion resolution.
• Output-load requirements.
• Isolation and protection characteristics.
• Host PLC and hardware compatibility.
• Terminal layout and wiring.
• Software configuration and scaling.
• Cabinet space and installation requirements.
• Spare-part availability and long-term support.

A modern module may offer improved diagnostics or broader functionality, but it should not be considered a direct replacement until the complete system has been checked.
