With CPX−AB−4−M12x2−5POL −R and CPX−M−4−M12x2−5POL the
metal thread is connected to FE
Tab.2/3: Pin assignment of I−module type CPX−4DE with sub−base
CPX−AB−4−M12x2−5POL(−R), CPX−M−4−M12x2−5POL
Recommendation for the 4−input module:
Use the Festo DUO cable in order to connect two sensors to
sockets X1 and X3 with one plug at low cost.
CPX−AB−4−M12x2−5POL −R ,
CPX−M−4−M12x2−5POL
The metal thread of these sub−bases is connected internally
with pin5 (functional earth FE).
