FAQ

1. Q: Can GE MS90376-12Y be directly used for high voltage circuit switching?
   A: It is used for control signal interlock, not for direct switching of high voltage main power circuit.
2. Q: What are typical module failure symptoms?
   A: Coil no pull-in, contact poor conduction, contact stuck, status feedback signal abnormal.
3. Q: How to complete commissioning and diagnosis?
   A: Check 24VDC coil power supply, test relay pull-in/release action, verify contact on-off continuity and status feedback signal.
