AS-Interface
ASI (Actuator Sensor Interface) is a field bus system that is used for networking (mainly) binary sensors
and actuators to a master controller.
Bus line
Unscreened pairs (ASI line as ASI format cable) over which both information (data) and energy (power
supplies for the sensors and actuators) are transmitted.
Network topology
Freely selectable within wide limits, i.e., star, tree and line networks are possible. Further details can be
found in the ASWI specification.
Bus connection variants
1. Flat cable clamp on the 1 m round cable
ASI standard connection:
2. 4-pole M12 plug on the 2 m round cable
ASI special connection 1: (on request)
3. 4-pole M12 plug on the control head, without cable
ASI special connection 2: (on request)
NOTE Data for the round cable
The electrical values of the round cable leading directly to the control head deviate slightly
from the ASI specification. When calculating the maximum permissible line length according
to the ASI specification, the length should therefore be set longer by the factor 1.5.
ASI length = 1.5 x real length
ASI PIN configuration
1 = ASI+
2 = not used
3 = ASI-
4 = not used
