2.5.2
Connection of the AS interface AUX power supply
The black cable is used for the power supply to the sensors. The AS interface supply cable is connected to the
AUX 24V and AUX GND terminals. The corresponding connection terminals on the particular AS interface
module are illustrated in Sections 2.1.2 / 2.2.2 / 2.3.2.
The AS interface modules have multiple supply terminals. These terminals are interconnected internally.
24V power supply AUX:
• AUX 24V : If the standard black cable is used, this is the brown wire.
• AUX GND : If the standard black cable is used, this is the blue wire.
2.5.3
Connection of the AS interface sensors and actuators
For the SK TU1/TU3-AS1 module the sensors and actuators are connected to connector 1 via terminals 3 to 8
(see Section 2.1.2 / 2.2.2 ). On the SK TU2-ASx module the connection is made via the I/O sockets 1 and 2.
The corresponding pin assignment is illustrated in Section 2.3.2 . The connecting cables should be laid
separately from the energy cables and kept as short as possible.
I/Os for sensors and actuators:
• Dig In 1-4
: digital inputs 1-4 for connection to the sensors
• Dig Out 1-2 : digital outputs 1-2 for connection to the actuators
2.5.4
Connection examples to SK TU2-ASx for sensors and actuators
In the following, 4 connection combinations to the SK TU2-ASx module for sensors and actuators by means of
standard connector systems (M12 components) are illustrated. The illustrations in a) and b) refer to the
connection of several sensors / actuators to a single I/O socket. Of course, two sensors can be each
connected to a separate I/O socket. Suitable connector systems are e.g. those from the firm Murr Elektronik:
a) 1 sensor:
The sensor can be connected directly to the I/O sockets by means of 4-pin M12 plugs.
b) 1 Sensor + 1 Actuator:
Use of a 4-pin M12 – M12 / Y-connection or T connector.
