Configured for discrete signal output in Modicon logic controller systems, the Schneider Electric TM3DQ32UK (TM3DQ32UK Discrete Output Module) provides direct physical electrical switching execution for 32 channels.

Identification and Model Configuration

The TM3DQ32UK is a high-density transistor output module designed for the Modicon TM3 I/O expansion series. It utilizes an HE-10 interface to manage 32 discrete outputs in a negative logic (sink) configuration, operating at a nominal 24 VDC.

Technical Performance Parameters

PLC System Integration Characteristics

The integration of this module within the Modicon M241, M251, M221, and M262 platforms relies on the internal bus backplane for both power and deterministic data exchange. Users must account for I/O density scaling when configuring the controller hardware profile to ensure the backplane power budget is not exceeded. Firmware compatibility is managed through the EcoStruxure Machine Expert environment, where the module is mapped to specific memory addresses upon insertion into the I/O bus topology.

Ordering Specifications

• 1 x TM3DQ32UK Discrete output module

• 1 x Installation instruction manual

• Note: HE-10 connector cabling is not included and must be sourced separately based on length requirements.

Field Deployment Procedures

• Mounting: Secure the module onto a symmetrical DIN rail (TH35-15 or TH35-7.5) using the integrated locking clip or install on a panel using the appropriate fixing kit.

• Wiring: Utilize shielded cables for signal integrity; ensure total cable length remains under 5 m for transistor outputs to prevent signal degradation and electromagnetic interference.

• Grounding: Maintain a common ground potential between the 24 VDC power supply and the controller system to prevent potential differences across the output channels.

• Environment: Ensure installation remains within the specified IP20 rating; avoid locations subject to condensation or excessive vibration exceeding 3 gn.

Technical Operational Queries

• Q: Can this module perform hot-swapping during operation?

  A: No, the TM3DQ32UK does not support hot-swapping. Power must be disconnected from both the controller bus and the field supply before module removal or installation.

• Q: What is the maximum load for a single channel?

  A: Each transistor output is rated for a maximum current of 100 mA.

• Q: Is there protection against inductive loads?

  A: Yes, internal circuitry limits leakage to 0.1 mA and supports a maximum tungsten load of 1.2 W. External flyback diodes are recommended for large inductive loads.

• Q: How is the output status monitored?

  A: Each of the 32 channels features a dedicated front-facing green LED indicating the active logic state of the output.

• Q: What is the purpose of the HE-10 connector?

  A: The HE-10 connector serves as the high-density interface for the 32 discrete output points, facilitating rapid connection via pre-wired terminal blocks or flying leads.

• Q: Does this module require an external power supply?

  A: While the internal bus provides power for electronics, the 24 VDC output load circuit must be supplied by an external regulated power source.

• Q: How does the module react during an over-temperature event?

  A: The module is rated for operation up to 55 deg C (horizontal). Exceeding this thermal threshold may result in internal component degradation or unpredictable output behavior.

• Q: Are the outputs galvanically isolated from each other?

  A: No, the 32 channels share a common return within the module; the 500 VAC isolation rating applies only between the channel group and the internal system bus.
