Schneider TM3DQ32UK Modicon TM3 32-Point NPN Transistor Output Module

Product Overview

When your automation system demands reliable, high-density discrete output control, the Schneider TM3DQ32UK delivers. This Modicon TM3 module provides 32 NPN transistor outputs with negative logic (sink), making it a natural fit for applications requiring low-side switching. As a maintenance engineer, you value components that simplify troubleshooting and reduce downtime. The TM3DQ32UK meets that need with clear LED status indicators per channel and a compact footprint that fits standard DIN rails or panels.

Technical Specifications Breakdown

The TM3DQ32UK offers 32 discrete outputs, each rated at 24 V DC and 100 mA. Its negative logic (sink) configuration means outputs are active when the internal transistor pulls the load to ground. Key electrical characteristics include a maximum leakage current of only 0.1 mA and a voltage drop below 0.4 V, ensuring efficient power delivery. Response times are a fast 450 µs for both turn-on and turn-off, suitable for most high-speed sequencing tasks. The module consumes 25 mA at 5 V DC and 40 mA at 24 V DC when outputs are on, with minimal consumption in the off state.

Installation & Setup Guidance

Mounting the TM3DQ32UK is straightforward. It snaps onto a standard TH35-15 or TH35-7.5 DIN rail per IEC 60715, or can be panel-mounted using an optional fixing kit. The HE-10 connector provides secure electrical connections for all 32 outputs. For reliable operation, keep unshielded cable runs under 5 meters. The module is IP20 rated with the protective cover in place, so install it inside an enclosure to protect against dust and accidental contact. Insulation between outputs and internal logic is rated at 500 V AC, but outputs are non-insulated from each other—plan your wiring accordingly.

Maintenance & Reliability

From a maintenance perspective, the TM3DQ32UK is built for longevity. Each output channel has a green LED for quick status verification, allowing you to spot a faulty channel without disconnecting wiring. The module operates reliably in ambient temperatures from -10 to 55 °C (horizontal installation) and withstands vibration up to 3 gn on DIN rail. Its solid-state transistor outputs eliminate mechanical wear, reducing the need for periodic replacements. For maximum uptime, simply ensure the enclosure stays within the specified temperature and humidity ranges (10-95% non-condensing).

Compatibility & Integration

The TM3DQ32UK integrates seamlessly with Schneider Electric's Modicon M221, M241, M251, and M262 logic controllers. It communicates via the backplane bus, drawing power and data from the controller. The module is CE, cULus, UKCA, RCM, and EAC certified, meeting global standards for industrial control equipment. When designing or expanding a system, pairing this output module with compatible input modules from the same Modicon TM3 series ensures consistent performance and simplified wiring.

Buying Guide & Purchasing Advice

Before ordering, verify that your controller supports the TM3 expansion bus and that your application requires NPN (sink) output logic.
