Potentiometer with Exciter Pin
Note:
Use the
Exciter
pin to increase the measurement accuracy of
the potentiometer. Not available on the UI/O module.
Analog 4-20 mA
Note:
The Analog (G) module does not support 4-20 mA.
To reduce electrical interference:
•
The connection
of
-Analog In
to
Cmn
should be
made as close as possible to the transducer.
•
Use individually shielded twisted-pair wire.
•
Connect cable shield to ground on one end only.
The
Res
and
-In
pins are
internally connected via
a 250
Ω
resistor.
To reduce noise, use
individually shielded
twisted-pair wire.
