Honeywell FSC 10302/1/1 Watchdog Repeater Module
The Honeywell FSC 10302/1/1 Watchdog Repeater Module is designed to monitor the 5 VDC and 24 VDC power supplies to I/O modules. It provides a watchdog output signal to ensure output modules operate within safe voltage conditions. It is crucial in configurations combining redundant and non-redundant I/O, or when the required watchdog current exceeds 900 mA.
