Differential input!
For an input signal referred to ground, terminal 4 must be connected to reference potential M.
Caution:
The voltage between an input (Kl.3 (Kl.10) or Kl.4 (Kl.11)) and the ground point 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 = 0, 1, 4 the units are V.
Possible settings p0756[0]:
= 0: 0 V ... +10 V
= 1: +2 V ... +10 V with monitoring
= 2: 0 mA ... +20 mA
= 3: 4 mA ... +20 mA with monitoring
= 4: -10 V ... +10 V (Default for AI0)
