Bently Nevada 3500/32 Series 4-Channel Relay Module

Overview

The 3500/32 4-Channel Relay Module is a full-height module providing four independent relay outputs for critical alarm and trip functions. Each output can be programmed using Alarm Drive Logic, combining AND/OR logic across multiple monitor channels to meet system-specific requirements.

Key Features

• Four independently programmable relay outputs

• Supports complex alarm logic via 3500 Rack Configuration Software

• Can be installed in any slot to the right of the Rack Interface Module

• Designed for continuous industrial operation with high reliability
