• Unused Input Channels
Turn on the excitation supply switch for the unused channels
and close across the unused input terminals with a resistor
(5 kΩ, 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.
