Oiltech Controls’s Insight

• This module fits well in legacy and new Twido systems.
• It is ideal for conveyor logic, packaging machines, and small PLC setups.
• The relay outputs handle moderate power loads directly.
• Spring terminals reduce wiring time compared to screw types.
• Common point design simplifies field wiring for inputs and outputs.

Suitable Equipment

• Schneider Twido series PLC bases (TWDLMDA, TWDLCAE, etc.)
• Small conveyor control panels
• Packaging and labeling machines
• HVAC and building automation controllers
• OEM machinery with relay actuator needs

Professional FAQ

• Q: Can I mix sink and source inputs on this module?
  A: Yes, the TWDDMM24DRF supports both sink and source logic per input group. This offers flexibility for different sensor types.
• Q: What is the total current limit for all relays combined?
  A: The common terminal per output group supports up to 7A. Distribute loads across both common groups to avoid overloading.
• Q: Does this module work with TwidoSuite and SoMachine?
  A: Yes, it is fully supported in TwidoSuite. For SoMachine, use it with compatible Twido bases via supported firmware.
• Q: How do I choose between relay and transistor outputs?
  A: Relay outputs handle AC/DC loads up to 2A, ideal for actuators. Transistor outputs are faster but DC-only. Choose based on load type and switching speed.
• Q: Is wiring polarity important for inputs?
  A: Since inputs are sink/source compatible, polarity depends on your sensor wiring. Use COM0_POS for sourcing and COM0_NEG for sinking.
