Product Overview

The Schneider Electric TSXDMZ28DT is a discrete solid-state I/O base module designed for the Modicon TSX Micro automation platform. This compact module provides 28 I/O points, making it suitable for small to medium-scale industrial control applications requiring reliable digital signal processing. The module is part of Schneider Electric's Modicon TSX Micro range, known for its compact design, ease of integration, and robust performance in factory automation environments. It is compatible with TSX Micro CPUs and can be mounted on a DIN rail or panel.

Key Features of TSXDMZ28DT

The TSXDMZ28DT features 16 discrete inputs with a 24 V DC positive voltage rating, compatible with 2-wire and 3-wire proximity sensors, mechanical switches, and other standard 24 V DC field devices. It includes 12 discrete solid-state outputs with 24 V DC and 500 mA per channel output current, suitable for controlling small solenoids, relays, and indicator lights. The module uses screw terminal blocks for secure field wiring connections, and a HE-10 connector is provided for additional I/O expansion. The solid-state outputs provide faster switching and longer life compared to relay outputs.

The module is powered by 24 V DC and has an operating temperature range of 0 to 55 °C. It is certified for CE, UL, and CSA standards, ensuring compliance with international safety requirements for industrial control equipment. The TSXDMZ28DT includes diagnostic LEDs for power and I/O status, facilitating rapid on-site troubleshooting. The compact design allows efficient use of panel space, making it ideal for control cabinets with limited real estate. The module is part of the Modicon TSX Micro automation platform, which provides a scalable solution for applications ranging from simple machine control to more complex automation tasks.

Functional Description

The TSXDMZ28DT communicates with the Modicon TSX Micro CPU via the internal backplane bus. Input channels monitor field device signals (e.g., pushbuttons, limit switches) and transmit their status to the CPU. Output channels receive control signals from the CPU and drive field actuators such as solenoid valves and contactors. The solid-state outputs provide fast switching with no mechanical wear, ideal for high-cycle applications. Diagnostic LEDs provide immediate visual confirmation of power status and I/O activity, speeding up commissioning and maintenance.

Applications

The TSXDMZ28DT is used in small to medium-scale industrial automation systems where compact, reliable digital I/O is required. Typical applications include packaging machinery, conveyor control, small assembly stations, material handling equipment, and machine tool auxiliary functions. It serves as a replacement module for existing Modicon TSX Micro systems or as a building block for new control panel designs.
