The analog input module AI43-N is used for

the connection of potentiometers in 3 or 4-

wire technology. If 3-wire potentiometers are

used, the terminals at the module rack have

to be bridged. Resistance measurements, i.e.

the evaluation of potentiometers with a 2-wire

connection, is not possible.

The module has four field circuits to control 3

or 4-wire potentiometers. The field circuits are

galvanically isolated from the power supply,

from the internal bus and from each other

Each potentiometer input is monitored for wire

break. The interruption of a single connection

line is securely detected, as well as any combination of interruptions occuring at the four

input connection lines. Short-circuit monitoring is not carried out. In case of a line error,

the programmed substitute value is immediately output and the output value is set to 'invalid-bit'. This state is maintained until valid

measured values are provided again.

The resolution is 14 bit. For clear reading, 0…

100 % is digitized and displayed in a range of

0…10000 (independent of the parametrized

measuring range) and transmitted to the host

system.
