Schneider TSXDMZ28DT Discrete I/O Module for TSX Micro PLCs

Product Introduction

When automation systems require reliable discrete I/O handling, the Schneider TSXDMZ28DT delivers robust performance within the Modicon TSX Micro automation platform. This discrete solid state I/O base DC module combines 16 inputs via a 1 HE-10 connector and 12 outputs through a screw terminal block, operating at 24 V DC. Designed for positive logic, it ensures seamless integration into existing control architectures.

Technical Specifications Breakdown

The TSXDMZ28DT operates on a 24 V DC supply, drawing 132 mA of current. Power dissipation is carefully managed: 3.5 W per module and 0.15 W per channel for outputs, plus 5 W for inputs. Input voltage limits require ≥ 11 V at state 1 and < 5 V at state 0, with guaranteed currents of ≤ 1.5 mA at state 0 and ≥ 2.5 mA at state 1. Output voltage ranges from 19 to 30 V, with a maximum output current of 0.625 A. Leakage current stays below 0.5 mA at state 0, and residual voltage is only 0.3 V. The module supports a switching frequency of < 0.6/LI² Hz and provides isolation voltage of 1500 V for 1 second. Response times are ≤ 0.5 ms for output transitions and 0.1 to 7.5 ms for input transitions.

Industry Applications

In manufacturing environments, the TSXDMZ28DT excels at controlling discrete actuators and reading sensor inputs. Its compatibility with 2-wire and 3-wire proximity sensors makes it ideal for material handling and packaging lines. The module's positive logic and robust output protection—including overvoltage protection via zener diode, short-circuit protection by current limiter and electronic circuit breaker, and reverse polarity protection—ensure reliable operation in demanding industrial settings.

Installation & Setup Guidance

Mount the TSXDMZ28DT securely within a TSX Micro PLC rack. Connect 24 V DC power to the module, observing polarity. For inputs, use the HE-10 connector; for outputs, the screw terminal block. Ensure input voltage meets the ≥ 11 V threshold for state 1 and stays below 5 V for state 0. Outputs can be paralleled up to a maximum of two for increased current capacity. Verify load impedance is 48 Ohm to match specifications.

Maintenance & Reliability

Regularly inspect the module for dust accumulation and ensure ambient temperature stays within -20°C to 55°C. The TSXDMZ28DT complies with IEC 1131-2 Type 1 environmental standards, guaranteeing durability in industrial conditions. Minimal leakage current (0.5 mA) and efficient power dissipation (3.5 W per module) reduce heat stress, extending service life. Periodic testing of input and output response times helps maintain system integrity.

Compatibility & Integration

The TSXDMZ28DT is designed exclusively for the Modicon TSX Micro automation platform. It integrates directly with TSX Micro PLCs, supporting discrete I/O control without additional adapters. The module uses positive logic for both inputs and outputs, ensuring straightforward programming and troubleshooting. For replacement or expansion, verify compatibility with your existing TSX Micro system.
