Product Overview

• PN: 3500/92 136180-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Machinery Protection System
• Type: Rack Communication Gateway Module

• Function: This module serves as the external data transmission hub of the entire 3500 rack. It collects real-time measurement data, alarm status and fault information from all monitoring cards through the rack backplane, then transmits data to upper control systems and configuration tools via Ethernet and serial interfaces. It supports customized Modbus register configuration to flexibly map monitoring parameters, and will not affect the hardwired trip protection function of each channel even during communication breakdown.
