FAQ
Q: Can this module handle analog signals?
A: No. The IS200WROBH1AAA is designed exclusively for relay output switching, not analog signal processing.
Q: What precautions are needed for installation?
A: Ensure correct wiring, grounding, and that the relay contact ratings match the controlled devices to maintain reliability and prevent contact wear.
Q: Are there similar modules in the IS200 family?
A: Yes. For example, the IS200AO (Analog Output) handles analog signals, while IS200DI (Digital Input) modules monitor discrete inputs.
