3RK1400-0CD00-0AA3 circuit diagram
With the 4I/4O module 3RK1400-0CD00-0AA3 for printed circuit
board mounting, it is possible for up to four mechanical contacts
to be queried or indicator lights to be operated, the necessary
energy being provided by the AS-Interface system (yellow
AS-Interface cable).
Note:
If the switching outputs are overloaded, the module does not
respond to invoking by a master.

3RK1400-0CD01-0AA3 circuit diagram
With the 4I/4O module 3RK1400-0CD01-0AA3 for printed circuit
board mounting, it is possible for up to four mechanical contacts
to be queried or indicator lights to be operated, the necessary
energy for the inputs and outputs being provided from the auxil-
iary voltage (24 V PELV). If (+) is connected to U
aux
+ and (NC)
to U
aux
–, the outputs are not short-circuit and overload proof;
if U
aux
– is connected to (0), the outputs are overload and short-
circuit proof (maximum summation current 200 mA). In this case,
the module does not respond even to invoking by a master when
the switching outputs are overloaded.
