3500/45 Position I/O Module

The Bently Nevada 135137-01 is a Position I/O Module with Internal Terminations designed for the 3500/45 Position Monitor in the 3500 Machinery Protection System. It serves as the rear-rack interface between field-mounted position sensors and the front-facing monitor module, conditioning raw signals from proximity transducers, Rotary Position Transducers (RPTs), and DC LVDTs for precise measurement of axial (thrust) position, differential expansion, case expansion, and valve position.
