The Bently Nevada 3500/42 135489-01 is a 4-channel I/O module designed specifically for the 3500/42M Proximitor®/Seismic Monitor, part of the industry-standard 3500 Machinery Protection System . This module serves as the critical interface between field sensors and the monitoring system, accepting inputs from proximity probes, seismic transducers, and accelerometers. The 135489-01 variant features internal safety barriers and internal terminations, making it the ideal choice for hazardous area installations . By integrating intrinsic safety circuitry directly onto the I/O board, this module eliminates the need for external Zener barriers or isolators, simplifying wiring, saving panel space, and reducing potential failure points.
