Product Overview

• PN: 3500/22-01-01-00
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Machinery Protection System
• Type: Standard Transient Data Interface (TDI) Front Module

• Function: Must be installed in Slot 1 next to rack power supply modules, combining the functions of traditional 3500/20 RIM rack interface and external TDXnet data collector in one single card. It communicates with all M-series monitoring modules via rack backplane, downloads system configuration parameters, collects real-time measurement values, alarm logs and fault codes, captures high-speed transient vibration waveforms during unit startup, trip and abnormal conditions, and transmits all data to System 1 diagnostic platform through Ethernet port. The module only undertakes data communication tasks and will not affect the hardwired trip protection of each monitoring channel even if communication fails.
