Schneider TM3DQ16T Modicon TM3 16-Output Transistor Module

Product Overview

In the evolving landscape of industrial automation, the demand for precise, reliable discrete output control has never been higher. The Schneider TM3DQ16T Modicon TM3 discrete output module meets this challenge head-on, providing 16 transistor outputs with positive logic (source) for seamless integration into modern control systems. Designed for compatibility with Modicon M221, M241, M251, and M262 controllers, this module delivers consistent performance in demanding environments.

Technical Specifications

The TM3DQ16T operates at 24 V DC for transistor outputs, with each channel capable of sourcing 500 mA. Its response time is 450 µs for both turn-on and turn-off, ensuring rapid actuation. The module consumes 5 mA at 5 V DC (state off) and 15 mA at 5 V DC (state on) via the bus connector, with 0 mA and 20 mA at 24 V DC respectively. Maximum leakage current is 0.1 mA, and voltage drop is less than 0.4 V. It supports unshielded cable distances up to 30 m for transistor outputs and includes one green LED per channel for output status indication.

Industry Applications

This module excels in applications requiring high-speed switching, such as conveyor sorting systems, packaging machinery, and assembly line actuators. In a typical scenario, the TM3DQ16T controls solenoid valves or indicator lights directly from a Modicon M241 PLC, reducing wiring complexity and improving response times. Its positive logic configuration simplifies integration with sourcing sensors and actuators common in North American installations.

Installation Guide

Mount the TM3DQ16T on a top hat TH35-15 or TH35-7.5 rail per IEC 60715, or on a panel using the fixing kit. Electrical connection uses a 10 x 1.5 mm² removable screw terminal block with 3.81 mm pitch. Ensure the module is installed within the ambient temperature range: -10 to 35 °C for vertical mounting, or -10 to 55 °C for horizontal mounting. Use shielded cable for distances over 30 m to maintain signal integrity.

Maintenance and Reliability

With no moving parts and solid-state transistor outputs, the TM3DQ16T offers long service life with minimal maintenance. Periodic inspection of connections and LED status indicators is recommended. The module withstands vibration up to 3.5 mm at 5–8.4 Hz and shock up to 15 gn for 11 ms, making it suitable for harsh industrial environments. Its IP20 protection degree requires a protective cover in place.

Compatibility and Integration

The TM3DQ16T integrates directly with Modicon M221, M241, M251, and M262 controllers via the bus connector. It complies with IEC 61131-2 standards and holds certifications including cULus, CE, UKCA, RCM, EAC, and cULus HazLoc. For system expansion, multiple TM3 modules can be daisy-chained to increase I/O count without additional wiring complexity.

Selection Guide

Before purchasing, verify that your controller supports the TM3 series and that the output voltage (24 V DC) and current (500 mA per channel) match your load requirements.
