MODEL: R3-SS4
Remote I/O R3 Series
CAUTION
■ UNUSED INPUT CHANNELS
Set the unused channels to -20 – +20 mA or 0 – 20 mA
range. Otherwise, set them as “Unused” with PC
Configurator software: R3CON. Unused channels left open
with 4 – 20 mA setting are equal to the input lower than -15
%, which sets a data abnormality at the PLC or the host
device.
