The GE Multilin 750-P5-G1-S1-HI-A20-R is a digital feeder management relay designed for the primary protection, control, and asset management of distribution feeders in solidly grounded, high impedance grounded, or resonant grounded systems. Equipped with a high-performance microprocessor architecture, flash memory for field upgrades, and real-time oscillography, the device provides integrated current, voltage, frequency, power, and energy metering to eliminate auxiliary metering equipment. Communication interface hardware includes a front RS232 port, dual rear RS485/RS422 ports, and supports Modbus RTU, Modbus TCP/IP, and DNP 3.0 Level 2 protocols over serial or optional 10Mbps Ethernet physical layers. The GE Multilin 750-P5-G1-S1-HI-A20-R processes inputs from 5 A phase CTs, 1 A zero sequence CTs, and 1 A sensitive ground CTs, generating output signaling via eight electromechanical output relays, one high-speed solid-state SCR output, and eight isolated 4-20 mA analog outputs.
