In any of the slots to the right of the Rack INTERFACE MODULE, any number of 4-Channel Relay Modules can be installed. The outputs can be independently programmed to perform required voting logic. Each relay has Alarm Drive Logic. The Alarm Drive Logic is programmed with AND and OR logic and can accept alarming inputs (alerts and dangers) from any monitor channel or combination of monitor channels in the rack. The 3500 is used in this Alarm Drive Logic programming.

OK LED: Illuminated when module is functioning properly.
TX/RX LED: Transmit and Receive. Flashes to indicate proper communications between this module and other modules within the rack.
CH ALARM LED: Illuminated when the Relay Channel is in an alarm state.
Environmental
Sealing: Epoxy-sealed
Arc Suppressor: 250 Vrms, installed as standard.
Contact Life: 100,000 cycles at 5 A, 24 Vdc or 120 Vac.
