125712-01 | Bently Nevada 3500/32 Spare 4-Channel Relay Module

Description:

The 125712-01 Bently Nevada 3500/32 Spare 4-Channel Relay Module is a full-height module that provides four relay outputs designed for use in 3500 monitoring systems. These relays can be independently programmed with "Alarm Drive Logic," utilizing AND and OR logic to respond to alarm inputs from monitor channels within the rack. This configuration is managed using the 3500 Rack Configuration Software, ensuring flexibility to meet specific application needs.
