TM3DQ16TK

The Schneider Electric TM3DQ16TK, also cataloged as the TM3DQ16TK discrete output module, provides 16 positive-logic PNP transistor outputs for 24 VDC signal control in Modicon TM3 expansion I/O systems. It connects to compatible Modicon M221, M241, M251, and M262 logic controllers through the expansion bus and uses HE-10 connectors for output wiring. Each output channel has a green status LED for local indication.

PNP Transistor Output Characteristics

The TM3DQ16TK switches 24 VDC field signals using 16 sourcing transistor outputs. Each channel supports a maximum output current of 100 mA, with a maximum ON/OFF response time of 450 us. The maximum leakage current is 0.1 mA, and the maximum output voltage drop is less than 0.4 V.

The HE-10 output connector provides the electrical interface to field devices. The specified maximum unshielded output cable length is 5 m. Applications must remain within the per-channel current rating and the controller's output logic configuration.

The module uses the Modicon TM3 expansion bus to exchange data and receive internal power. Its interlocking assembly mechanism supports physical integration with compatible TM3 modules and Modicon logic controllers.

Frequently Asked Questions (FAQ)

Q: Which Modicon controllers are compatible with the TM3DQ16TK?

A: The module is listed as compatible with Modicon M221, M241, M251, and M262 controllers. Confirm the controller model, firmware, and engineering software compatibility before installation.

Q: What are the output current and response-time limits?

A: Each transistor output supports up to 100 mA. The maximum specified response time is 450 us for both turn-on and turn-off. The load must remain within the channel rating.

Q: What isolation and cable-length limits apply?

A: The specifications list 500 VAC isolation between outputs and internal logic, 1500 VAC between outputs and supply, and 500 VAC between channels and the bus. The maximum specified output cable length is 5 m using unshielded cable.

Field Installation Guidelines

1. Mounting: Install the module on a TH35-15 or TH35-7.5 DIN rail compliant with IEC 60715, or use the specified panel-mounting fixing kit. Engage the interlocking mechanism with adjacent compatible modules.
2. Power isolation: Disconnect control power before wiring or removing the module. Follow the controller and system manufacturer's procedures for safe installation.
3. Output wiring: Connect field loads through the HE-10 interface. Verify PNP/source logic and confirm that each load remains within the 24 VDC and 100 mA per-channel ratings.
4. Cable routing: Keep output cables within the specified 5 m maximum. Route signal wiring away from high-current conductors and switching noise sources where practicable.
5. Grounding and shielding: Follow the controller and machine grounding design. The specified output cable is unshielded; do not substitute shielded wiring requirements without checking the applicable installation documentation.
6. Environmental conditions: Maintain the applicable temperature limit for the installation orientation. The enclosure provides IP20 protection, so install the module in an enclosure suitable for the site's environmental conditions.
7. Commissioning: Verify bus communication, output channel assignment, load current, and the green channel status LEDs before returning the equipment to service.
