• Unused Input Channels

Close across the unused input terminals with a resistor (5kΩ, 0.5W) as shown below.

Unused channels left open are equal to the input lower than -15%, which sets a data abnormality at the PLC or the host device.

Unused channels can be specified and set so on the PC Configurator Software (model: R3CON) without needing to connect

resistors at the field terminals.
