IUx− = Negative voltage input signal
IIx+
= Positive current input signal
IIx− = Negative current input signal
FE = Functional earth
1)
Assignment depends on the DIL switch setting and on parametrizing (see section 2.3.1), a total of
2 input channels are available per module (I..0 and I..1, connection X1 or X2 as well as
connection X3 or X4).

CPX−AB−4−M12x2−5POL(−R)
CPX−AB−4−M12x2−5POL −R The metal thread (...−R") of this sub−base is connected
internally with pin 5 (Functional earth FE).
