Product Description
The 3500/42M-01 is a Triplex Voter Monitor Module from the Bently Nevada 3500 Monitoring System. This specialized module is designed for critical machinery protection applications where maximum reliability and fault tolerance are required. It accepts inputs from three independent sensors monitoring the same parameter and uses a voting logic (typically 2-out-of-3 or 3-out-of-3) to generate alarm and shutdown signals. This redundant architecture ensures that a single sensor or channel failure does not cause unnecessary machinery shutdowns while maintaining protection against genuine dangerous conditions.
