The Bently Nevada 3500/32M 149986-02 4-Channel Relay Module is a full-height relay module designed to deliver flexible, programmable control within the Bently Nevada 3500 Machinery Protection System. Each module features four independent relay outputs, making it ideal for managing alarms, shutdowns, and other critical machine control functions.

This relay module can be installed in any open slot to the right of the Transient Data Interface (TDI) module in a standard 3500 rack. Each output can be individually configured using Alarm Drive Logic (ADL) to support both AND and OR logic operations, enabling complex voting logic across multiple monitoring channels.

Tailor each relay to respond to Alert, Danger, Not-OK, or Proximitor Phase Logic (PPL) signals from one or more monitor channels using the 3500 Rack Configuration Software. This powerful configuration flexibility ensures that the module can meet a wide range of machine protection and control requirements.

Key Features:

• Provides four programmable relay outputs per module

• Supports AND/OR logic for advanced Alarm Drive Logic (ADL)

• Each relay can execute custom voting logic independently

• Accepts logic inputs from Alert, Danger, Not-OK, or PPL signals

• Integrates with any 3500 monitor channels within the same rack

• Easily configured using Bently Nevada 3500 Rack Configuration Software
