Bently Nevada 84152-01 3300/20 Quad Relays Module

Description

The Bently Nevada 84152-01 is a Quad Relays Module designed as a spare relay module assembly for the Bently Nevada 3300/20 Dual Thrust Position Monitor. The 84152-01 provides output relay switching functionality for monitoring systems within the Bently Nevada 3300 Series. Installed as part of the monitor assembly, it interfaces with the monitoring system to support alarm output signaling for machinery protection. Note that AND voting logic is not available directly within the module with Quad Relays; AND voting logic must be performed externally by wiring the contacts in series. Quad Relays are not compatible with the Internal Safety Barriers option.

Features
