Description
The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module.
Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic.
Each relay of the module includes Alarm Drive Logic. Programming for the Alarm Drive Logic uses AND and OR logic and may use the following:
•Alarming inputs (alert and danger statuses)
•Not-OK
•Individual Measured Variables from any monitor channel or any combination of monitor channels in the rack
You can program the Alarm Drive using the 3500 Rack Configuration
Software.
