Bently Nevada 3500/32-01-01 Relay Output Module

The Bently Nevada 3500/32-01-01 is a hot-swappable relay output module designed for the 3500 machinery protection system. It receives threshold alarm signals from monitoring modules and drives independent relay contact outputs to execute machinery safety interlock and field alarm control.

This module provides multiple configurable relay channels with built-in contact surge suppression. It supports flexible programming of alert and danger logic and complies with API 670 standards. Widely deployed in energy and petrochemical sectors for turbomachinery monitoring cabinet maintenance, system expansion and spare parts stocking.
