Product Overview
The Schneider TSXDMZ16DTK Modicon TSX Micro Discrete Solid State I/O Base DC combines discrete input acquisition and solid-state output switching in a single I/O module for compatible Modicon TSX Micro automation systems. It provides 8 digital inputs and 8 transistor outputs, allowing a PLC to monitor field sensors while controlling connected DC devices.
The eight 24 V DC positive-logic inputs acquire signals from compatible 2-wire and 3-wire proximity sensors, limit switches and other switching devices. The eight static outputs switch compatible DC loads according to the PLC program, making the module suitable for small machines that require both feedback signals and direct control outputs.
An HE-10 connector supports grouped field wiring, while a separate power connection supplies the module’s output circuit. This arrangement helps organize sensor and actuator connections in a control cabinet. During system design, the input signal characteristics, output current demand and external load protection requirements should be checked against the connected field devices.

Working Principle
The TSXDMZ16DTK receives field signals through its eight discrete input channels. Each input evaluates the incoming 24 V DC signal against the module’s logic thresholds. When the signal reaches a valid ON or OFF state, the corresponding input information becomes available to the TSX Micro PLC program.
The input response time can be configured from 0.1 to 7.5 ms for transitions in either direction. This setting affects how quickly input changes are recognized, so it should match the sensor characteristics and the machine’s sequence requirements. Signals that fail to meet the guaranteed voltage or current thresholds may be interpreted incorrectly.
The module’s eight solid-state outputs switch compatible 24 V DC loads in response to PLC commands. Each output is rated at 0.5 A, so the load current and switching conditions must remain within the specified limits. Inductive loads may require suitable suppression components, and the output supply must be wired according to the module’s connection instructions.
During commissioning, technicians should test the input and output channels separately. First confirm that field sensors produce the expected PLC input states, then command each output and verify that the connected actuator or load responds correctly. If an output does not operate, check the output supply, wiring, load current and PLC command state before replacing the module.
Role in a Modicon TSX Micro Control Architecture
The TSXDMZ16DTK provides a combined field-interface layer between a Modicon TSX Micro PLC and connected sensors and DC actuators. The input channels deliver machine-state information to the controller, while the output channels execute commands generated by the PLC application.

Technical FAQs
What should be checked when the TSXDMZ16DTK detects an input signal intermittently?
Measure the sensor signal at the module terminal and compare it with the specified ON-state and OFF-state thresholds. Check the selected input response time, sensor leakage current, field supply stability and connector contacts before changing the PLC logic.
Can the module directly operate a 24 V DC solenoid valve?
It can operate a compatible DC load only when the load’s steady-state and switching requirements remain within the output ratings. Verify coil current, inductive switching behavior and suppression requirements before connecting the valve directly.
Why might an input operate correctly while its associated output does not switch?
Input acquisition and output switching are separate functions. Check the PLC program condition, output command state, output supply connection, field wiring and connected load current to determine where the command path is interrupted.
What information is needed when replacing the TSXDMZ16DTK in an existing TSX Micro machine?
Confirm the exact I/O arrangement, input logic, output voltage and current requirements, connector pinout, output supply wiring and PLC channel assignments. Test every input and output after replacement to verify that the original machine sequence behaves as expected.
