When using a potentiometer and 10 V input voltage as the
maximum value, you must ensure that with a connected
input voltage of 24 V, 14 V must release via the series resi-
stor so that a maximum of 10 V are supplied when you turn
the potentiometer one full rotation. With a voltage of 12 V,
this can be neglected.
Note
The LOGO! AM 2 expansion module provides further
analog inputs. The LOGO! AM 2 PT100 expansion module
provides Pt100 inputs.
Always use twisted and shielded cables for analog signals,
and keep these as short as possible.

The inputs of these devices not
isolated and therefore require a
common reference potential
(chassis ground ).
At the LOGO! 12/24RC/RCo and
LOGO! 24/24o modules, you can
tap analog signals between the
supply voltage and chassis ground
(* = series resistor with 24 V DC).
