INPUT CONNECTOR (40-pin)
• Unused Input Channels
Close across the unused input terminals with a resistor as
shown below and set the DIP switch for an RTD. The
resistance value must match the RTD type (100
Ω
for Pt
100, 50
Ω
for Pt 50).
Unused channels left open are equal to the burnout, which
turns the red ERR LED on and sets a burnout flag at the
PLC or the host device.
Unused channelscan be specified and set so on the PC
Configurator Software (model: R3CON) without needing to
connect resistors at the field terminals.
