Integrated rack interface and high-speed transient data acquisition card replacing standalone 3500/20 RIM and TDXnet unit, equipped with Ethernet and serial ports to upload steady-state values and vibration waveform data to System 1 software, essential core communication module for 3500 TSI machinery protection rack, fully tested surplus spare parts

Product Overview

• PN: 3500/22M, Part No: 138607-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Machinery Protection TSI System
• Type: Transient Data Interface (TDI) Front Module
• Function: This module must be installed in Slot 1 next to rack power supply slots, integrating all core functions of 3500/20 RIM rack interface and TDXnet transient data processor into one single card without occupying extra rack slots. It communicates with all M-series monitor boards via rack backplane bus, downloads rack configuration parameters through official software, collects real-time measurement data, alarm logs and fault codes. Meanwhile it captures high-speed transient vibration waveforms during unit startup, coastdown and abnormal trips, transmits all data to System 1 predictive maintenance platform via Ethernet TCP/IP and RS232 serial interface. It outputs global system status relay signals, and does not interfere with local hardwired trip protection of each monitoring channel even if communication fails.

Core Features

1. Combines RIM rack management and high-speed waveform capture, eliminates need for external TDXnet equipment and extra wiring
2. Dual communication ports: RJ45 Ethernet 10/100BASE-TX and 9-pin RS232 serial port, supporting BN proprietary TDI communication protocol
3. Front panel key lock switch prevents unauthorized modification of rack configuration parameters
4. LED indicators display power status, data transmission, transient data recording and configuration running state
5. Hot-swappable design, online replacement available under dual redundant rack power supply configuration
6. Built-in large-capacity on-board memory to store transient event waveforms and historical alarm records for offline analysis
7. Full compatibility with all 3500/05 rack chassis and M-series monitor modules including 3500/40M, 3500/42M, 3500/53 overspeed card

8. Comprehensive self-diagnosis detects bus communication faults, module hardware errors and abnormal network connection automatically
