The Siemens 6AG2135-6HB00-1DA1 SIPLUS ET 200SP Analog Output Module is a two-channel high-speed analog output module in the SIPLUS extreme RAIL product family. Its detailed designation is AQ 2xU/I HS RAIL, based on the standard ET 200SP module 6ES7135-6HB00-0DA1. The SIPLUS version incorporates conformal coating and extended environmental qualifications for installations subject to demanding operating conditions.
The module converts digital output values from the controller into analog voltage or current signals for connected actuators. Typical applications include commanding proportional valves, regulating drive references and controlling other devices that accept analog setpoints. Its high-speed functions support isochronous output operation and oversampling, allowing output updates to be coordinated with time-sensitive automation tasks.
With two configurable analog output channels, the module supports several voltage and current ranges. It integrates into an ET 200SP distributed I/O station using a compatible BaseUnit type A0 or A1. Correct output-range selection, actuator wiring and controller configuration are essential to achieving the intended control response.

The module receives digital setpoint values from the automation controller and converts them into analog electrical signals. Each output channel can be configured for a supported voltage or current range, depending on the connected actuator and the control task.
For example, a controller can calculate a target position or flow command and send the corresponding output value to the module. The module generates the configured analog signal, which the actuator interprets as a reference for its operation. A voltage signal may be used for a drive reference, while a current signal such as 4–20 mA may be used by a proportional control device or another compatible industrial actuator.
The high-speed functions support output updates synchronized with the automation cycle or oversampling requirements. These functions are useful when output timing affects the behavior of the controlled process. They must be configured in the engineering environment and supported by the overall automation setup.
Correct output-range selection and wiring are essential. A mismatch between the configured signal and the actuator input can cause an incorrect command, a limited operating range or an unexpected response. Channel diagnostics should also be reviewed when the output does not behave as expected.
The 6AG2135-6HB00-1DA1 forms the analog command-output layer of a distributed control station. It translates controller-generated values into electrical signals for connected actuators, allowing the PLC to influence physical process variables.

AQ identifies an analog output module, 2x indicates two output channels, U/I denotes voltage and current output capability, and HS identifies the high-speed function class.
Supported ranges include 0–10 V, 1–5 V, -5–+5 V and -10–+10 V for voltage, and 0–20 mA, 4–20 mA and -20–+20 mA for current. The selected range must match the connected actuator and the channel configuration.
Isochronous output operation and oversampling are relevant when output timing or rapid updates are important to the control task. They should be enabled only when the controller, station configuration and application requirements support the chosen mode.
Verify the configured output range, channel assignment, wiring polarity where applicable, actuator input requirements and controller setpoint scaling. Review the module’s diagnostic information and measure the actual output signal before replacing the module.
