The Bently Nevada 3500/92 133323-01 is a communication gateway module designed to bridge the 3500 Machinery Protection System with external systems such as DCS, SCADA, or PLC-based platforms. It provides robust communication capabilities via Modbus RS-485 and serial interfaces, making it essential for plants that require secure, accurate, and real-time machinery data integration.
Its primary role is to transmit monitored parameters — such as vibration levels, temperature, speed, alarms, and equipment statuses — from the 3500 rack to supervisory control systems. This enables centralized monitoring and rapid diagnostics, reducing unplanned downtime.
