PLCs, Power Supplies & Others

The TSXDMZ28AR from Schneider Electric serves as an integrated discrete relay I/O base within the Modicon Premium automation platform. This versatile module combines both input and output capabilities into a single compact unit for space-efficient control applications. Its relay output design provides isolated switching for inductive loads such as contactors, solenoids, and motor starters. Consequently, engineers can control high-power field devices directly without requiring interposing relays or external interface modules.

Weighing approximately 1.43 lbs (0.65 kg), the TSXDMZ28AR features a rugged construction suitable for standard Premium rack mounting in industrial control cabinets. The module accepts 24 VDC inputs while providing relay outputs rated for various AC and DC load voltages. This mixed I/O configuration makes it ideal for machine control applications requiring both sensor input acquisition and actuator output control. Additionally, the unit operates reliably across temperatures from 0°C to 60°C, ensuring consistent performance in demanding manufacturing environments.

Comprehensive I/O Configuration

The TSXDMZ28AR provides a balanced I/O count with multiple input channels and corresponding relay output channels for typical machine control requirements. Its discrete inputs accept 24 VDC signals from proximity sensors, limit switches, and pushbuttons without additional signal conditioning. The relay outputs feature isolated contacts capable of switching both AC and DC loads up to their maximum rated current and voltage. These robust outputs eliminate the need for external solid-state relays or contactors in many standard applications.

Advanced Isolation and Diagnostic Features

This relay I/O base incorporates optical isolation between the backplane and input circuits, protecting the Premium processor from field-side voltage transients. The relay outputs provide mechanical isolation between channels, allowing mixed voltage types on different output points within the same module. Built-in LED indicators deliver immediate visual confirmation of each input and output state during normal machine operation. These diagnostic features enable maintenance personnel to quickly verify I/O status without specialized software or handheld tools.
