13 Electrical connection
In order to address the two digital inputs "In W" and "In X" a
resistor (R=1.2KΩ±5%) must be connected in series with the
input according to the circuit diagram. The switching levels
are >11mA for a High-Signal and <8mA for a Low-Signal.

13.8.2 Optional digital inputs
In the design with the option of two additional digital inputs,
the product has a total of four digital inputs, whereby the set
value and actual value input can continue to process ana-
logue signals.
The actual value and set value input can be used as a digital
input under the following circumstances:
Control system Operating
mode
Set value in-
put as digital
input "in W"
Actual value
