6.4.7 Wiring analog inputs AI

Damage to the device and sensors!
Incorrectly connected and configured analog inputs/outputs may result in
damage to the device and sensor.
► Follow information about connecting analog sensors.
► Configure analog inputs and outputs according to the connected sensors.
You can connect the following types of analog sensors:
▪ 0/4...20 mA
▪ 0 to 10 V
▪ PT100/PT1000 (2-wire, 3-wire, 4-wire) indirectly via measuring transducer
In order to correctly record the analog signals, you must place the cable
shielding on the grounding bar. The cable shielding should only be removed
just prior to connecting to ensure that the section with unshielded cables is
kept as short as possible. The shielding must be connected with shielding
clips.

1. Lead the wires into the connector and fasten them using a screwdriver.
2. Insert the plug into the respective slot in accordance with the connection
diagram [►Section 10.14, Page 68] and screw into place.

6.4.8 Wiring digital inputs DI

If you use digital inputs, these have to be supplied with an auxiliary voltage
of 110 V DC.
1. Feed the wires into the terminal of the DI 16-110V plug in accordance with
the connection diagram [►Section 10.14, Page 68] and fasten them us-
ing a screwdriver.
2. Plug the connector into the respective slot and screw it into place.
