Caution:
The voltage between an input (Kl.50) and the ground point (Kl.51) must not exceed 35 V.
When the load resistor is switched in (DIP switch in position I), the voltage between the input terminals
must not exceed 10 V or the impressed current 80 mA.
For p0756 = 2, 3 the units are mA.
For p0756 = 6, 7 the units are °C.
Possible settings p0756[2]:
= 2: 0 mA ... +20 mA (Default for AI2)
= 3: 4 mA ... +20 mA with monitoring
