■ Overview
3RK1 400-0CD00-0AA3
AS-Interface communications module for printed circuit
board installation
With the 4I/4O module for printed circuit board mounting it is
possible for up to four mechanical contacts to be queried or in-
dicator lights to be operated, the necessary power being pro-
vided 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.
3RK1 400-0CD01-0AA3
AS-Interface communications module for printed circuit
board installation
With the 4I/4O module for printed circuit board mounting it is
possible for up to four mechanical contacts to be queried or in-
dicator lights to be operated, the necessary power for the inputs
and outputs being provided from the auxiliary voltage (24 V
PELV). If (+) is connected to U
aux
+ and (NC) to U
aux
-, the out-
puts are not
short-circuit and overload resistant; if U
aux
- is con-
nected to (0), the outputs are overload and short-circuit resistant
(maximum summation current 200 mA). In this case the module
does not respond even to invoking by a master when the switch-
ing outputs are overloaded.
