6.3 Analog inputs
The first analog input is a fixed 4..20mA input.
The two other analog inputs are definable using plug-in analog conditioning modules
(ACM’s). (Any combination is possible)
It is strongly recommended to use shielded cable for analog inputs. Use the fastons
near the analog inputs for connection of the cable shield. Shielding connections must
be as short as possible. Avoid long “pig tails”, as this will reduce EMC performance.

6.3.1 ACM type 1: digital input on analog connector
The analog inputs can act as a digital input when an ACM type 1 is used. The contact
is connected between the common (C) of the analog input, and the analog input. A
voltage free contact must be used.
6.3.2 ACM type 2: 0-10Vdc voltage input
A 0-10Vdc voltage can be used where the source is closely located to the basic
controller. Use earth-shielded cable no greater than 2m in lengths. Note that a 4-20mA
is a much better choice regarding EMI and distance.
+V means a positive voltage to analog ground (A GND). The signal voltage can be
different from the supply voltage of the external sensor.
