Features:
- Mixed-I/O role: non-isolated field inputs and relay switching share one CS31 station module.
- Protection boundary: relay contacts depend on correctly selected external circuit protection.
- Response behavior: the fixed input delay must be accepted as part of the controller timing design.
The module bridges field-contact monitoring and relay-based switching, making both input commons and output loads part of the same service record.
Because the relay contacts are not internally short-circuit protected, cabinet protection and load suitability define whether reconnection is acceptable.
The full FPR identity, CS31 address, controller mapping, and terminal schedule must agree before the station returns to service.
