Product Overview

• PN: 3500/22M
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Turbomachinery Protection TSI System
• Type: Transient Data Interface (TDI) Main Module

• Function: Must be installed in Slot 1 next to rack power supply, merges traditional 3500/20 RIM rack interface and TDXnet data acquisition into one unit. It communicates with all M-series monitor boards through backplane bus, downloads system configuration parameters, gathers real-time measurement values, alarm logs and fault codes, captures high-speed transient vibration waveforms during unit startup, trip and abnormal conditions, and uploads all data to System 1 diagnostic platform via Ethernet. It only undertakes data communication tasks and will not interfere with hardwired safety trip of each channel even with communication failure
