The Bently Nevada 140471-02 is an I/O module designed for dynamic pressure monitoring applications in the 3500 Machinery Protection System. The module processes signal inputs from high-temperature pressure transducers to perform signal conditioning and pass data to the 3500/64M main monitor board. Featuring internal termination wiring connections, the 140471-02 routes transducer signals, provides transducer power supplies, and outputs proportional +4 to +20 mA recorder signals for external control systems.
