TSXDMZ28DR Overview: A Discrete Relay I/O Base for TSX Micro PLCs

The TSXDMZ28DR is part of the Modicon TSX Micro automation platform, engineered as a discrete relay I/O base. It provides 16 discrete inputs via screw terminal blocks, making it easy to wire and maintain. The module supports both 2-wire and 3-wire proximity sensors, offering flexibility in sensor selection.

With an isolation voltage of 1500 V for 1 second, the TSXDMZ28DR helps protect connected equipment from voltage transients. The normally open (NO) contact configuration is a common choice for many control applications, simplifying integration with existing relay logic.

Key Technical Specifications of the TSXDMZ28DR

Understanding the electrical characteristics of the TSXDMZ28DR is essential for proper system design. The module operates with a discrete input voltage of 24 V DC (negative logic) and a discrete input current of 9 mA. Input voltage limits are ≤ 8 V at state 1, with guaranteed current thresholds of ≤ 1.5 mA at state 0 and ≥ 2.5 mA at state 1.

Input impedance is rated at 4 Ohm, and the response time ranges from 0.1 to 7.5 ms for state transitions. For outputs, the module handles resistive loads with output voltage limits of 10 to 34 V DC and 19 to 264 V AC. Power dissipation is 4.5 W, and current consumption is 160 mA positive and 131 mA negative.

Here are the critical specs at a glance:

• Discrete input number: 16 screw terminal blocks
• Discrete input voltage: 24 V DC (negative)
• Discrete input current: 9 mA
• Output voltage limits: 10...34 V DC, 19...264 V AC

Application Scenarios: Where the TSXDMZ28DR Excels

In manufacturing plants, the TSXDMZ28DR can be used to interface with limit switches, proximity sensors, and relay outputs. Its wide output voltage range makes it adaptable to both DC and AC loads, which is common in mixed-technology facilities. For example, a packaging line might use the module to control solenoid valves and indicator lights.

In the oil and gas sector, reliability is paramount. The TSXDMZ28DR's robust isolation and clear electrical specifications make it suitable for remote monitoring and control applications. Maintenance teams appreciate the screw terminal connections, which allow for secure wiring and easy replacement without special tools.

Customer Scenario: A Maintenance Engineer's Perspective

Imagine a maintenance engineer at a mid-sized chemical plant who needs to upgrade an aging control panel. The existing PLC lacks sufficient I/O points, and the engineer chooses the TSXDMZ28DR to expand capacity. The module's 16 inputs and relay outputs integrate seamlessly with the existing TSX Micro PLC, reducing installation time.

During commissioning, the engineer verifies the input response time of 0.1 to 7.5 ms, which meets the process requirements. The normally open contacts provide a fail-safe configuration for critical alarms. Over time, the module's consistent performance reduces unplanned downtime, justifying the investment.

Compatibility and Integration with TSX Micro PLCs

The TSXDMZ28DR is specifically designed for the Modicon TSX Micro automation platform. This ensures seamless integration with other TSX Micro modules, simplifying system design and expansion. The screw terminal blocks provide a reliable connection point for field wiring, which is crucial in vibration-prone environments.

Because the module is part of the TSX Micro family, you can mix and match I/O modules to meet your exact requirements. This modularity allows for cost-effective scaling as your process evolves. Always verify compatibility with your specific PLC model before ordering.

Market Impact and Business Value

Investing in reliable I/O modules like the TSXDMZ28DR can significantly reduce lifecycle costs. The module's robust design minimizes the need for frequent replacements, and its clear specifications simplify troubleshooting, saving valuable engineering time. In industries where downtime costs thousands per hour, the TSXDMZ28DR's dependable performance is a smart investment.

Furthermore, the wide output voltage range (10...34 V DC, 19...264 V AC) means you can standardize on one module for various loads, reducing spare parts inventory. This flexibility is particularly valuable for maintenance teams managing multiple sites.
