Product Details
The 3500/92-04-01-01 is a communication gateway module designed by Bently Nevada for the 3500 Machinery Protection System. It collects monitored machinery health and operational data from the 3500 rack backplane and translates it into Modbus protocol, enabling seamless data integration with plant control systems like DCS or PLC networks. This specific configuration features an Ethernet/RS485 Modbus I/O card, a low memory allocation card, and CSA/NRTL/C hazardous area certification.
Network Communication Interfaces
The -04 I/O module option combines Ethernet and RS485 physical layer interfaces on a single card assembly. It supports both Modbus TCP/IP over Ethernet networks and Modbus RTU over RS485 serial communication lines, providing flexible connectivity to host systems for real-time monitoring of vibration values, alarm states, and rack diagnostic status.
