• Unused Input Channels
Close across the unused input terminals with a resistor
(5k
Ω
, 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.
