Product Detail

High voltage AC power input rear termination card matched with 3500/15 front power module 127610-01, 175–264Vac power wiring terminal for 3500 TSI rack redundant power supply, surplus spare parts for turbomachinery monitoring system

Product Overview

PN: 125840-01
Brand: Bently Nevada (Baker Hughes)
Series: 3500 Machinery Protection TSI System
Type: High Voltage AC Power Input Module (PIM Rear Card)
Function: Dedicated rear power termination board paired with front AC power module 3500/15 (127610-01). It provides high-voltage AC wiring terminals, receives 175–264Vac industrial mains input and transmits power to the front power supply unit, then converts to stable multi-channel DC bus voltage for all rack monitoring, communication and relay modules. Multiple PIM cards support 1+1 redundant power backup layout of the whole rack.

Core Features

Designed for high voltage AC input 175–264Vac, fits standard industrial 220V plant power grid
Matches half-height 3500/15 front power module, front-rear paired installation in rack left power slots
Built-in overvoltage, short-circuit fuse protection, automatically cut off abnormal input to protect rack backplane
Screw-type wiring terminals, stable connection for long-term continuous industrial operation
Hot-swappable rear slot installation; redundant power configuration allows single PIM replacement without rack power failure
