3500/33 16-Channel Relay Module
Datasheet
Bently Nevada Machinery Condition Monitoring
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:
l Alarming inputs (alert and danger statuses)
l Not-OK
l 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.
