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

Overview

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.
