Product Overview

• PN: 3500/22M, Part No: 138607-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Turbomachinery Protection TSI System
• Type: Standard Transient Data Interface (TDI) Front Module
• Function: Mandatorily mounted in the first slot adjacent to rack power supply units. It combines the functions of traditional 3500/20 rack interface module and TDXnet data acquisition processor. It interacts with all M-series monitoring modules through backplane bus, downloads system configuration parameters, collects real-time measured values, alarm logs and fault codes, captures high-resolution transient vibration waveforms during unit startup, trip and abnormal operation, and transmits all data to System 1 predictive maintenance platform through matched rear I/O card. It only undertakes data forwarding tasks, and the hardwired safety interlock of each channel will not be affected even if communication is interrupted。

Core Features

• Occupies a single rack slot without extra space for separate communication equipment
• Front panel equipped with RJ45 Ethernet port, RS232 serial debugging port and USB configuration interface
• Front panel key lock prevents unauthorized modification of rack system configuration
