Schneider TM3DQ32UK 24V Transistor Output Module

Schneider TM3DQ32UK Transistor Output Module

Product Introduction

The Schneider Electric TM3DQ32UK expands your control system with 32 discrete outputs. Each channel uses NPN transistor technology with negative (sink) logic. This module fits perfectly with Modicon M221, M241, M251, and M262 controllers.

Additionally, the TM3DQ32UK switches loads at 24V DC with 100 mA per output. The HE10 connector simplifies high-density wiring. Response time reaches just 450 µs for both turn-on and turn-off operations.

For reliable performance, the maximum voltage drop stays below 0.4V. Leakage current remains at 0.1 mA when the output is off. Consequently, you can drive small solenoids, indicator lamps, or solid-state relays directly.

Technical Specifications of TM3DQ32UK

Output characteristics determine how the TM3DQ32UK performs in real applications. The module provides 32 transistor outputs with one common return path. All outputs share negative logic, meaning they switch the ground side of your load.

Moreover, local signalling includes one green LED per channel. Each LED lights up when its corresponding output is active. This gives you instant visual feedback during commissioning and troubleshooting.

Current consumption reaches 25 mA at 5V DC from the bus when outputs are on. When all outputs are off, it drops to 5 mA at 5V DC. The TM3DQ32UK also draws 40 mA at 24V DC from the bus in the on state.

Insulation between outputs and internal logic withstands 500V AC. However, the Schneider Electric TM3DQ32UK does not isolate outputs from each other. Therefore, all 32 outputs share the same voltage reference.

Mechanical & Environmental Data

The TM3DQ32UK measures 33.5 mm wide, 90 mm high, and 81.3 mm deep. Net weight equals 0.112 kg. Mounting options include TH35-7.5 or TH35-15 DIN rails, or a plate using a fixing kit.

Operating temperature ranges from -10°C to 55°C for horizontal mounting. Vertical installation reduces the maximum to 35°C. Storage temperature spans -25°C to 70°C. Relative humidity can reach 95% without condensation.

Furthermore, vibration resistance reaches 3.5 mm at 5–8.4 Hz, then 3g up to 150 Hz. Shock resistance stands at 15g for 11 ms. The IP20 rating applies only when the protective cover is in place.

The TM3DQ32UK carries multiple certifications including cULus HazLoc, CE, UKCA, RCM, and EAC. It also meets marine specifications from LR, ABS, DNV, and GL.

Output Wiring Guidelines for TM3DQ32UK

First, understand the sink (NPN) logic of the TM3DQ32UK. Connect the positive 24V DC supply to your load's common terminal. Then, connect the other side of each load to the corresponding output channel.

When the output turns on, the Schneider Electric TM3DQ32UK connects the load to 0V DC. The load energizes because current flows from +24V through the load into the output.

For best results, keep unshielded cables shorter than 5 meters for transistor outputs. Use shielded cable if you run near inverters or heavy contactors. Add a flyback diode across inductive loads like relays or small solenoids.

Next, configure your Modicon controller to recognise the TM3DQ32UK in the I/O map. Test each output by turning it on and watching the green LED confirm the state.

Installation Guidelines

First, disconnect all power before handling the TM3DQ32UK. Clip it onto a DIN rail until it locks securely. Alternatively, mount it on a panel using the optional fixing kit.

Next, connect the HE10 cable between the TM3DQ32UK and your field devices. Ensure each output stays within the 100 mA maximum current. Exceeding this limit may damage the transistor.

Finally, leave space for ventilation, especially in vertical mounting. The TM3DQ32UK generates minimal heat but still needs airflow in a crowded cabinet.

Frequently Asked Questions (FAQ)

1. What loads can I drive with the TM3DQ32UK?
The TM3DQ32UK handles 100 mA at 24V DC per channel. Typical loads include LEDs, small relays, solenoids, and solid-state relays. For larger loads, add an interposing relay.

2. Why is the cable length limited to 5 meters for transistor outputs?
Transistor outputs switch quickly (450 µs). Long unshielded cables act as antennas and can cause false triggering. Keep cables under 5 meters for reliable operation.

3. Can I use the TM3DQ32UK with PNP (source) devices?
No, the TM3DQ32UK uses negative (sink/NPN) logic only. For PNP outputs, please use the TM3DQ32TK or another source-type module.

4. What happens if I short an output to ground?
The Schneider Electric TM3DQ32UK does not have short-circuit protection. A direct short may damage the transistor. Always use an external fuse (100 mA fast-blow) for critical loads.

5. Does the module support hot swapping?
No, do not remove or insert the TM3DQ32UK while the system is powered. Always turn off the controller bus power first to prevent damage.
