Product function

Bently Nevada 84145-01 serves as an aggregation hub, receiving conditioned transducer outputs and buffering them for distribution. Routes analog signals to chart recorders or DCS analog inputs via screw-terminal blocks. Provides isolated dry contacts for alarm, trip, or sequence-of-events logging while maintaining signal fidelity at 200 kHz.
