Frequently Asked Questions about 760-P5-G5-S5-LO-A20-R
Does the 750/760 GE Feeder Management Relay 760-P5-G5-S5-LO-A20-R have communication ports?
The 750/760 GE Feeder Management Relay 760-P5-G5-S5-LO-A20-R has two communication ports in the back of the relay that can be used at the same time. The two communication ports support the subset of the AEG Modicon Modbus that is a protocol.
What mode is used for the two communication ports on the 760-P5-G5-S5-LO-A20-R?
The first communication port (COM1) is used with modes RS485 with two wires and also the mode RS422 is used with four wires. But COM1 won't work in both modes simultaneously. The second communication port (COM2) is only used with the two wire RS485 mode.
Can I minimize error by using a shielded twisted pair wire on the GE Feeder Management Relay?
Yes, using a shielded twisted pair wire is recommended to minimize errors that make noise. If the SR type relays are connected with the B1 terminals that are connected together and all the B2 terminals are connected together, terminal B3 has to be connected to the common wire on the shield that is on the inside.
