<1> Differential Input!
For an input signal referred to ground, Kl. 4 (Kl. 11) must be connected to reference potential M.
Notice:
The voltage between inputs and between input 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. If this is not observed, the input will be damaged.
<2> For p0756 = 2, 3 the units are mA.
Kl. = Terminal For p0756 = 0, 1, 4 the units are V.
