End of line resistors EOLR are resistors of a known value that are used to terminate protective loops or zones such as those found in Fire and Gas FG systems and some Emergency.

. The graphic symbol is an arrow line with two arrows inward added to the graphic symbol of the ordinary. By adding a 120-ohm resistor at the end of an RS485 transmission line the signal will be dampened by the resistor instead of reflected into the bus. Should be at the last device.

EOL is a line termination resistor used for the RS485 Modbus RTU communication cable. End of line resistors EOLR are resistors of a specified value that are used to terminate protective loops or zones. Up to 15 cash back EOL stands for End of Line.
