Keyphasor I/O Module

The Bently Nevada 125800-01 is a Keyphasor I/O Module with internal terminations for the 3500/25 Enhanced Keyphasor system. It serves as the rear I/O card that works in conjunction with the 149369-01 Enhanced Keyphasor Module (main card), providing the physical connection interface for Keyphasor transducer inputs from proximity probes or magnetic pickups. 

The Bently Nevada 3500/25-02-03-01 (135473-01) is a Keyphasor I/O module with internal barriers and internal terminations, designed for use with the 3500/25 Enhanced Keyphasor Module. Its core function is to provide signal isolation and termination for Keyphasor transducers, converting raw pulses from proximity probes or magnetic pickups into clean digital Keyphasor signals. This isolated I/O module is specifically intended for applications where multiple devices share Keyphasor signals simultaneously and isolation from other systems (such as a control system) is required to prevent electrical interference and ground loop issues.
