Products Description
Bently Nevada 3500/32 125712-01 Relay Output Module in stock
Bently Nevada 3500/32 125712-01 is a 4-channel relay output module for the Bently Nevada 3500 machinery protection system. It receives alarm and trip signals from monitoring modules and outputs dry relay contacts to external systems for local annunciators, PLC interlock and emergency trip circuits of rotating machines.

This module features isolated relay contacts and hardware fault detection, supporting hot-swap operation without interrupting the rest of the monitoring rack. It is widely used for turbine protection cabinet maintenance, spare parts replacement and rotating machinery safety monitoring retrofit projects.
