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.
