Bently Nevada 3500/42M P/N：176449-02
Full name: Proximitor/Seismic Monitor Four Channel Displacement/Velocity/Acceleration Monitoring Module (Front Card)
Baker Hughes 3500 Unit TSI Protection System Multi functional Monitoring Card

1、 Basic Overview
3500/42M is the most compatible monitoring card in the 3500 series, and one card supports three major types of sensors simultaneously; Channels are grouped in pairs (1&2, 3&4), and the two groups can independently configure different measurement types.
📌 Complete set of mandatory requirements: The front card 176449-02 must be paired with the corresponding I/O rear card before it can be loaded onto the machine
Common matching terminal modules:
128240-01: External European style terminal (most commonly used in projects)
128229-01: Built in terminal version
⚠️ Match the front and rear part numbers in a complete set, and do not mix and match them randomly
2、 Support sensors and configurable measurement projects
✅ Eddy current probe (3300XL)
Radial shaft vibration, axial displacement, eccentricity, differential expansion, REBAM relative bearing motion
✅ Velomitor speed sensor
Vibration velocity of bearing shell
✅ Piezoelectric accelerometer
Shell acceleration, rotor absolute vibration
3、 Core hardware specifications
Channel: 4 independent signal inputs
Panel configuration: 4-channel BNC buffer signal output, convenient for external acquisition/oscilloscope
Alarm mechanism: Each channel has an independent Alert warning and a two-level Danger threshold
Analog output: Independent 4-20mA recorder output for each channel, connected to DCS
Indicator lights: OK, communication TX/RX, bypass status
Power consumption: Typical 7.7W, powered by the 3500 rack backplane
Installation: 3500/05 rack single slot, supports hot swapping
Standard: Meets API 670 and supports SIL2 security protection applications
Working temperature: -20 ℃~+70 ℃
4、 Key model differentiation (procurement focus)
3500/40M 176449-01
Only supports eddy current sensors and cannot be connected to speed/acceleration sensors
3500/42M 176449-02 (this model)
Three in one universal card: compatible with eddy current, speed, and acceleration
Industry common misconception: Do not abbreviate as 3500/42, the complete model is 3500/42M
5、 Two wiring schemes
Built in terminal solution: Connect the I/O card directly without the need for external terminal blocks
External wiring scheme (mainstream for large units)
I/O rear card → 129525 dedicated cable → 125808-02/125808-05 external terminal block → on-site sensor
