Input module type CP−E16−KL−IP20−Z provides PNP or NPN
inputs. You can determine either PNP or NPN operation by
installing an external bridge in the sensor supply connection.

A separate load supply for the valves/outputs can be looped
through via pins 7 and 8. By means of the other internal
bridges (24 V, FE, 0 V), the relevant potential can be passed
on to the next CP module.
