Bently 125800-01 specialized wiring interface module

Bently 125800-01 is a specialized wiring interface module developed by Bently Nevada (now part of GE Vernova), exclusively designed for the 3500 Series Rotating Machinery Monitoring System. It serves as a standardized connection hub between field sensors (e.g., eddy current displacement sensors, accelerometers) and the 3500 system’s core monitoring modules (such as vibration, keyphasor, or temperature monitoring modules). Its core value lies in simplifying on-site wiring, enhancing signal integrity, and protecting the system from field-side electrical risks (e.g., short circuits, interference). Below is its detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Applicable System	Dedicated to Bently Nevada 3500 Series Monitoring System (compatible with 3500/10, 3500/20 frames)
Terminal Configuration	24-channel terminal design (each channel includes independent signal, power, and ground pins), supporting both single-ended and differential signal wiring
Signal Compatibility	- Analog signals: 4-20mA current signals (sensor outputs), ±10V voltage signals (transmitter outputs), microvolt-level eddy current sensor signals- Digital signals: Dry contact status signals, open-collector speed signals
Electrical Isolation	- Channel-to-channel isolation: 500V AC (rms, 1 minute)- System-side (3500 module) to field-side (sensor) isolation: 1kV AC (rms, 1 minute)
