The Bently Nevada 3500/42M 176449-02+128229-01 is a four-channel Proximitor Seismic Monitor designed for machinery protection by continuously comparing monitored vibration and position parameters against configured alarm setpoints. The system consists of the 3500/42M main monitor board (176449-02) and the Prox/Seismic I/O module with internal terminations (128229-01). Channels are programmed in pairs using 3500 Rack Configuration Software to perform up to two functions simultaneously, including radial vibration, thrust position, differential expansion, eccentricity, REBAM, acceleration, velocity, shaft absolute, and circular acceptance region. The module processes signal inputs from proximity, velocity, or acceleration transducers, providing continuous parameter conditioning and driving alert and danger alarms.
