Expert FAQ and Selection Guide
- Q: Can I mix sink and source inputs on this module?
- A: The module operates via one common point, so all inputs must follow the same logic configuration.
- Q: How do I select the right input module for my controller?
- A: Match the voltage requirements and logic type specifically to your existing PLC I/O map.
- Q: Does the module require external power for the logic?
- A: The controller powers the internal logic, but the inputs require a dedicated 24V DC supply.
