This unit is built with the optional 10BaseT Ethernet port. This can help you connect your unit to 10 Mbps Ethernet networks. The 10BaseT port is in addition to the three standard serial ports that are built into SR469 units. There is a single RS232 port located in the front panel. This allows for quick programming and troubleshooting. Additionally, there are two more RS485 ports in the rear panel of the relay. The three serial ports support ModBus RTU protocol. With the addition of the Ethernet port, the SR469 also supports ModBus RTU via TCP/IP protocol.
469 Relays are designed to offer voltage and frequency protection, protection against ground faults through two dedicated ground current inputs, load loss detection, reverse active power, current unbalance, and overtorque to protect the load from mechanical breakage.
