Pin assignment of sockets
The following diagram shows the pin assignment
of all the inputs in socket form using inputs I0.00
and I0.01 as examples.
Input

of sockets Internal
connection of pins Explanation
Upper row
Bridge between
pins 2 and 4
Lower row
Bridge between
pins 4,2
(socket upper row) and
Pin 2
(socket lower row)
Advantage:
Two inputs on lower
socket (here I0.00 and
I0.01), thereby
•
fewer cables,
•
connection to
changeover switch
or
converter possible.
Please note:
If the lower socket is
used for two input cables,
the upper socket must
remain unused.
(see example 2, p. 4-46).
