Product Description

Critical Machinery Protection and Logic Control

The 3500/33 (Model: 3500/33) is a high-density relay output module designed for the Bently Nevada 3500 Machinery Protection System. The 149992-01 (Part Number: 149992-01) provides sixteen independent relay channels, serving as the primary interface for triggering alarms, enunciators, and emergency machinery shutdown sequences. This module is essential for implementing sophisticated voting logic (e.g., 2-out-of-3 or 1-out-of-2), allowing process engineers to automate protection responses based on vibration, position, or temperature setpoints across multiple monitoring modules.
