Connecting the Signal Input Cables
This section describes how to connect the signal input cables.
CAUTION
During wiring, confirm that the signal's supply source is turned OFF to prevent electrical shocks.
Also, position the GL860 input cable away from any power lines and ground cables.

CH1
Ex: The current is converted to the voltage in the shunt resistor.
For 4 to 20mA current input, installing 250 ohms (0.1%) resistor for converting 1 to 5V.
