Product Overview
When your industrial control system demands reliable discrete I/O handling, the Schneider TSXDMZ28DR discrete relay I/O base delivers consistent performance. Designed for the Modicon TSX Micro automation platform, this module provides 16 discrete inputs via screw terminal blocks, making it easy to integrate into existing wiring schemes. The TSXDMZ28DR operates with a 24 V DC negative logic input voltage, ensuring compatibility with standard industrial sensors and switches.
Technical Specifications Breakdown
The TSXDMZ28DR offers a robust set of electrical characteristics. Its isolation voltage reaches 1500 V for 1 second, providing adequate protection against transient surges. The module uses normally open (NO) relay contacts and supports output voltage limits of 10 to 34 V DC and 19 to 264 V AC, covering a wide range of load types. Power dissipation is rated at 4.5 W, while current consumption measures 160 mA positive and 131 mA negative. Input impedance is 4 Ohm, with input current limits of ≤ 1.5 mA at state 0 and ≥ 2.5 mA at state 1. Input voltage limits are ≤ 8 V at state 1. The response time ranges from 0.1 to 7.5 ms for both state transitions, ensuring quick switching for time-sensitive processes.
Industry Applications
In manufacturing environments, the TSXDMZ28DR excels at controlling resistive loads such as indicator lights, small solenoids, and contactors. Its compatibility with 2-wire and 3-wire proximity sensors makes it ideal for part detection and position sensing on assembly lines. The module's wide output voltage range allows it to interface with both DC and AC actuators, reducing the need for separate interface modules.
Installation & Setup Guidance
Mount the TSXDMZ28DR securely on a DIN rail within your TSX Micro PLC rack. Connect field wiring to the 16 screw terminal blocks, ensuring proper torque for reliable connections. For input wiring, use shielded cables for long runs to minimize noise. Verify that the 24 V DC supply is negative logic compatible as specified. Always power down the system before making or changing connections.
Maintenance & Reliability
Periodically inspect the terminal blocks for signs of corrosion or loose wires. The module's resistive load design reduces contact wear, extending relay life. Keep the enclosure clean and free of dust to maintain adequate airflow for the 4.5 W power dissipation. Check insulation resistance periodically; the specification requires ≥ 10 mOhm.
Compatibility & Integration
The TSXDMZ28DR integrates seamlessly with the Modicon TSX Micro automation platform. It is compatible with 2-wire and 3-wire proximity sensors, making it suitable for a variety of input devices. The module's output voltage range allows direct connection to many AC and DC actuators without additional signal conditioners.
Selection Guide & Purchasing Advice
Before ordering, verify that your system uses 24 V DC negative logic inputs and requires 16 discrete input points. The TSXDMZ28DR is a discrete relay I/O base, not an analog module, so ensure your application needs discrete control. SpareTechPLC stocks this module and can confirm current lifecycle status and availability.
