31.3 Wiring topic
Two analog inputs can be wired to connector X1. A measuring range of 4 –
20 mA with open wire monitoring is supported, as is a measuring range of 0
– 20 mA without open wire monitoring.
The current input channels use a differential voltage measurement at an
internal module resistor with a resistance of 50 .
It must be ensured that the input signals' voltage levels fall within the
permissible common mode range.
Two analog outputs for a burden resistance of less than 500  can be wired
to connector X2.
