4.1.2 Connecting the Analog Inputs
Only shielded cables may be connected to the analog inputs. Each analog input must be
connected to a twisted pair of wires. The shielding must be connected to the controller and the
sensor housing and earthed on the controller side to form a Faraday cage.
Necessary shunts must be connected directly to the inputs of the module.
The inputs are connected using 9-pole connectors with numbered terminals. The terminal pins
on the front plate of the module have the same numbered sequence to avoid invalid
connections.
Use the following terminals to connect the analog inputs:
Terminal Designation Function
1 I1+ Analog input 1
2 I- Ground input 1
3 I2+ Analog input 2
4 I- Ground input 2
5 I3+ Analog input 3
6 I- Ground input 3
7 I4+ Analog input 4
8 I- Ground input 4
9 Ground / shielding
Terminal Designation Function
10 I5+/I1- Analog input 5
11 I- Ground input 5
12 I6+/I2- Analog input 6
13 I- Ground input 6
14 I7+/I3- Analog input 7
15 I- Ground input 7
16 I8+/I4- Analog input 8
17 I- Ground input 8
18 Ground / shielding
Table 10: Terminal Assignment for the Analog Inputs
 Unipolar inputs:
I1+ and I-, I2+ and I-, I3+ and I-, I4+ and I-, … I8+ and I-
 Bipolar inputs
I1+ and I5+/I1-, I2+ and I6+/I2-, I3+ and I7+/I3-, I4+ and I8+/I4-
All I- terminals are interconnected.
