Product Overview

• PN: 3500/22M, Part No: 138607-01AE
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Machinery Protection TSI System
• Type: Upgraded Revision Transient Data Interface (TDI) Front Module

• Function: AE suffix represents revised hardware and optimized firmware edition based on base model 138607-01, fully compatible with all 3500/05 rack chassis and M-series monitoring modules. It must be mounted in Slot 1 adjacent to rack power supply slots, integrating core functions of traditional 3500/20 RIM rack interface and independent TDXnet transient data processor within a single slot without extra hardware occupation. It communicates with all monitor boards via backplane bus to download configuration parameters, collect real-time measurement values, alarm logs and fault information. Meanwhile it captures high-speed transient vibration signals during unit startup, trip and abnormal conditions, and transmits all data to System 1 predictive maintenance software through Ethernet TCP/IP and RS232 serial channel. The module outputs global rack system OK relay signals, and all hardwired trip protection of each monitoring channel operates independently even if this communication module fails, without threatening unit safety interlock.

Core Features

1. AE upgraded revision fixes minor hardware compatibility bugs, expands on-board storage for transient waveform recording and improves long-term operation stability
2. Integrated dual communication interfaces: 10/100M Ethernet RJ45 port and 9-pin RS232 serial port, supports BN proprietary TDI communication protocol
3. Front panel key lock switch prevents unauthorized modification of rack configuration parameters and parameter tampering
4. Multi-group LED indicators clearly display power supply status, bus communication, transient data recording and configuration running status
5. Hot-swappable structure allows online replacement without rack power cut under dual redundant power supply configuration
6. Large-capacity onboard memory stores historical alarm events and transient waveform data for offline equipment fault analysis
7. Perfectly matches all 3500 M-series monitor modules including 3500/40M, 3500/42M, 3500/44M, 3500/45 and 3500/53 overspeed card

8. Comprehensive self-diagnosis mechanism automatically detects backplane bus faults, module hardware errors and network link exceptions
