The 1-channel potentiometer amplifier

IM36-11EX-U/24VDC is designed to transmit

signals from 3 or 5-wire potentiometers galvanically isolated from the Ex area to the nonEx area and to converted them into normalized 0…10 V analog signals. The resistance

value of the wiper contact, ranging from 0 ò

to the nominal resistance value (final value)

of the potentiometer, is detected and linearly

processed.

A potentiometer is defined by its nominal resistance value. Any potentiometer can be connected, provided the nominal resistance is

800 … 20000 ò. Common potentiometers

featuring a nominal resistance of 1 kò or 10

kò can thus be used. The admissible line resistance is maximally 50 ò with a potentiometer resistance of 800 ò.
