Wiring Diagram
* While it is possible to use different resistive ranges, we recommend using the
narrowest range that covers the resistance being measured. For example,
if measuring approximately 100 ohms resistance, use the 0 to 195.31ohms
range. While the resolution is the same as the 0 to 390.62 ohms range,
output RMS noise will be lower and stability will be improved.
These COM terminals are
isolated.
NOTE: The C0-04RTD module cannot
be used with thermistors.
NOTE: When using this module you
must also use CLICK programming
software and PLC ο¬rmware version
V1.40 or later.
If there are any unused channels,
make sure to select the correct
number of channels that you
actually use in the C0-04RTD
Setting window.
