MPORTANT:
Remember the following:
•
If separate power sources are used, do
not exceed the specific isolation
voltage. For more information on
module specifications, see the 1756
ControlLogix I/O Specifications
Technical Data, publication
•
Terminals 1, 2, 35, and 36 are not
used in RTD applications.
•
For 2-wire resistor applications
including calibration, make sure
IN_x(-)/B and IN_x/RTD C are
shorted together.
