FAQ

1. Q: Can IC660TBD025 be used with source type I/O electronic blocks?
   A: It is sink configuration terminal base, only compatible with matching sink electronic blocks, not for source modules.
2. Q: What are typical terminal base failure symptoms?
   A: Genius bus communication lost, channel no response, LED status abnormal, poor wiring terminal contact.
3. Q: How to complete commissioning and diagnosis?
   A: Check field DC power and bus wiring, use test port to verify channel status, adjust input filter parameter and confirm bus communication.
