Silent Knight 5883 (Relay Interface Board, 10 Form C Relays)

The 5883 Relay Interface Board provides ten general-purpose Form C relays for controlling external circuits that require a dry-contact closure. It is driven by an open-collector input from a controlling device such as the 5880 LED I/O Module, enabling functions like elevator recall, door release, and HVAC shutdown within a Silent Knight system.
