Description

The Bently Nevada 149992-01 is a 16-Channel Relay Output Module designed for integration into the 3500 Machinery Protection System. This full-height module provides sixteen independently programmable SPDT (Single Pole Double Throw) relay outputs, converting machinery protection events into hardwired control signals for external automation, safety systems, and equipment interlocking. It is a critical component for managing alarm annunciation and shutdown control in rotating machinery monitoring applications.

Features

  • 16 independent SPDT relay outputs.
  • Full-height rack module design.
  • Configurable Alarm Drive Logic using AND/OR operators.
  • Supports inputs from Alert, Danger, and Not-OK statuses.
  • Programmable via 3500 Rack Configuration Software.

Applications

  • Nuclear, thermal, and hydroelectric power generation plants.
  • Turbine monitoring (bearings and stator windings).
  • Pump and motor protection (winding and bearing housing temperature monitoring).
  • Gearbox lubrication and internal friction monitoring.
  • General industrial equipment protection (fans, blowers, extruders).
