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

The Bently Nevada 125712-01 4-Channel Relay Module, a compact and versatile industrial control device from the USA, offers four isolated relay outputs with a 24 VDC voltage rating. You can configure these relays as normally open or closed. It’s compatible with the Bently Nevada 3500/32 vibration monitoring system and holds CE and RoHS certifications. Weighing 0.5 kg with dimensions of 100 x 70 x 40 mm, this module is ideal for controlling motors, solenoid valves, alarms, and equipment monitoring in industrial settings. It comes with a 1-year warranty for added reliability.

Description:

The module provides four relay outputs.
Multiple modules can be placed in the slots to the right of the Rack Interface Module.
Each relay can be independently programmed for specific logic.
Alarm Drive Logic is programmed using AND and OR logic, with inputs from monitor channels in the rack.
It is compatible with the 3500 Rack Configuration Software for customization.
Note: TMR applications require a different module – the 3500/34 TMR Relay Module.
