The 1-channel potentiometer amplifier

IM36-11EX-I/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…20 mA 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.
