Product Detail

4-channel universal monitoring card compatible with eddy current probes, velocity & acceleration sensors; internal termination design paired with 128229-01 rear I/O card, for turbomachinery vibration, thrust displacement and bearing vibration protection, surplus tested spare parts for 3500 TSI system

Product Overview

PN: 3500/42M, Part No: 140734-02
Brand: Bently Nevada (Baker Hughes)
Series: 3500 Machinery Protection TSI System
Type: Multi-Function Proximitor & Seismic Monitor Module (Internal Termination Version)
Function: 4-channel programmable monitor supporting three types of sensors (eddy current proximity probe, Velomitor velocity transducer, ICP accelerometer). Channels are grouped in pairs (CH1+CH2 / CH3+CH4), configurable to measure radial vibration, thrust position, differential expansion, shaft eccentricity, bearing vibration and shaft absolute vibration. It generates Alert/Danger two-stage alarm signals and 4-20mA analog output, uploading real-time operating data to upper monitoring platform for rotating equipment safety interlock and fault early warning. 140734-02 corresponds to internal termination front board, must match rear I/O card 128229-01 for field wiring connection

Core Features

Four fully independent programmable channels, flexible paired measurement configuration, supports up to 2 different monitoring tasks on one module
Complies with API 670 industrial standard, supports TMR triple redundant safety architecture for critical unit protection
Front-panel 4 BNC buffered signal outputs, allowing on-site waveform inspection and signal debugging without system shutdown
Comprehensive built-in self-diagnosis: detect sensor open circuit, short circuit, module failure and rack bus communication anomaly
Hot-swappable rack installation; front LED indicators clearly display power status, running state and channel alarm trigger
Modbus register address editable via official configuration software, convenient for data docking with DCS and PLC systems
