The 4-Channel Relay Module is a full-height module that provides four relay

outputs. Any number of 4-Channel Relay Modules can be placed in any of the
slots to the right of the Rack Interface Module. Each output of the 4-Channel
Relay Module can be independently programmed to perform needed voting
logic.

Each relay utilized on the 4-Channel Relay Module includes "Alarm Drive Logic".
The Alarm Drive Logic is programmed using AND and OR logic, and can utilize
alarming inputs (alerts and dangers) from any monitor channel or any
combination of monitor channels in the rack. This Alarm Drive Logic
programming uses the 3500 Rack Configuration Software to meet the specific
needs of the application.
