TM3DQ32UK Overview
The TM3DQ32UK from Schneider Electric is a high-density discrete output module belonging to the Modicon TM3 family. It provides 32 transistor outputs with negative logic (sink), making it a reliable choice for controlling a wide range of industrial actuators, indicators, and small loads. As part of the Modicon TM3 platform, this module integrates seamlessly with Modicon M221, M241, M251, and M262 programmable logic controllers (PLCs).
With a compact form factor of 90 mm height, 81.3 mm depth, and 33.5 mm width, the TM3DQ32UK saves valuable panel space while delivering robust performance. Its net weight of just 0.112 kg simplifies handling and installation. The module uses a HE-10 connector for outputs, ensuring secure and organized wiring.
Key Technical Specifications
The TM3DQ32UK is engineered for precise and dependable output control. Below are the critical specifications extracted from the official datasheet:

These specifications demonstrate the module’s ability to handle moderate DC loads with fast switching times. The negative logic (sink) configuration is particularly suited for applications where the load is connected to the positive side of the supply, and the module switches the ground path.
Industry Applications
The TM3DQ32UK excels in various automation scenarios. Its 32 outputs allow for controlling multiple devices simultaneously, which is common in packaging machinery, material handling systems, and assembly lines. For example, in a bottling plant, the module can manage solenoid valves and indicator lamps across multiple stations, reducing the need for multiple smaller modules.
In addition, the module’s fast response time (450 µs) makes it suitable for applications requiring quick actuation, such as sorting systems or pick-and-place units. The ability to mount on standard DIN rails (TH35-15 or TH35-7.5) simplifies integration into existing control panels.
Installation & Setup Guidance
Mounting the TM3DQ32UK is straightforward. It can be installed on a top hat TH35-15 rail or TH35-7.5 rail conforming to IEC 60715, or on a plate or panel using a fixing kit. Ensure that the module is properly seated and secured to avoid vibration issues. The module’s vibration resistance is tested up to 3 gn at 8.4–150 Hz on both DIN rail and panel, and shock resistance up to 15 gn for 11 ms.
When wiring, use the HE-10 connector for output connections. Keep unshielded cable lengths under 5 meters to maintain signal integrity. For optimal performance, follow the wiring guidelines provided in the Modicon TM3 documentation. Always verify that the power supply matches the required 24 V DC for transistor outputs.
Maintenance & Reliability
The TM3DQ32UK is designed for long-term reliability in industrial environments. Its operating temperature range is -10…55 °C for horizontal installation and -10…35 °C for vertical installation. Storage temperature ranges from -25…70 °C. The module can operate at altitudes up to 2000 m and store up to 3000 m.
To ensure consistent operation, periodically inspect the module for dust accumulation or loose connections. The IP20 protection rating (with protective cover) means it should be installed in a clean, dry enclosure. Regular checks of the output status LEDs can help quickly identify any channel issues.
Compatibility & Integration
The TM3DQ32UK is fully compatible with Modicon M221, M241, M251, and M262 PLCs. This broad compatibility allows you to standardize on one output module across multiple machine platforms, simplifying spare parts inventory and reducing training requirements. The module communicates with the PLC via the bus connector, drawing minimal current from the backplane.
When integrating, ensure that your PLC’s output mapping is configured for negative logic (sink) operation. The module supports a maximum tungsten load of 1.2 W per output, which is important when driving incandescent lamps.
Selection Guide & Purchasing Advice
Before ordering the TM3DQ32UK, verify that your application requires 32 transistor outputs with sink logic. If you need source logic (positive), consider a different module. Also, check the output voltage and current ratings to ensure they match your loads.

Troubleshooting & Common Issues
If an output channel fails to activate, first check the LED indicator for that channel. If the LED is off, the issue may be in the PLC program or wiring. If the LED is on but the load does not operate, verify the load supply voltage and that the load current is within the 100 mA limit.
Leakage current can cause false activation in sensitive loads. The TM3DQ32UK has a maximum leakage current of 0.1 mA, which is generally negligible, but for high-impedance loads, consider adding a pull-down resistor. Also, ensure that the total current consumption via the bus connector does not exceed the PLC’s capacity.
Frequently Asked Questions
What is the difference between sink and source outputs?
The TM3DQ32UK uses negative logic (sink), meaning the output transistor switches the ground path. The load is connected between the positive supply and the output terminal. This is opposite of source outputs, which switch the positive path.
Can I use the TM3DQ32UK with a Modicon M221 PLC?
Yes, the TM3DQ32UK is listed as compatible with Modicon M221, M241, M251, and M262 PLCs. It connects via the bus connector and is configured in the PLC software.
What is the maximum cable length for the outputs?
For unshielded cable, the maximum distance is less than 5 meters. For longer runs, use shielded cable or consider remote I/O solutions.
How do I know if an output is active?
Each channel has a green LED that illuminates when the output is on. This provides immediate visual feedback for troubleshooting.
Is the TM3DQ32UK suitable for inductive loads like relays?
Yes, but ensure the load current does not exceed 100 mA. For inductive loads, consider adding a flyback diode to protect the transistor from voltage spikes.
