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.

Q1: What is the primary function of the 135137-01?
It is the rear I/O module for the 3500/45 Position Monitor. It receives raw analog signals from position sensors (proximity probes, RPTs, DC LVDTs), provides excitation power, and routes conditioned signals to the main monitor card for comparison against user-programmable alarm setpoints.
Q2: Can this module accept AC LVDT or rotary potentiometer inputs?
No. The 135137-01 supports proximity probes, RPTs, and DC LVDTs only. For AC LVDT applications, the 139554-01 module is required; for rotary potentiometers, the 139978-01 module is needed.
Q3: How are the channels configured?
The monitor channels are programmed in pairs. Channels 1 and 2 can perform one function while channels 3 and 4 perform another (or the same) function. Case expansion can only be performed on channels 3 and 4.
Q4: Is the 135137-01 hot-swappable?
No. Always de-energize the rack before inserting or removing the I/O module to prevent backplane or sensor damage. Follow proper lockout/tagout procedures and use ESD protection .
Q5: What is the difference between 135137-01 and 135145-01?
The 135137-01 uses Internal Terminations (field wiring connects directly to the module's built-in terminal blocks). The 135145-01 uses External Terminations (field wiring connects to separate external terminal blocks, with a cable linking to the I/O module).
