The AL2-ASI-BD Actuator Sensor Interface board module is used in conjunction with α2
series controller for data communication over an Actuator Sensor Interface (AS-interface)
network.
Further information can be found in the
α2 Series Programming Manuals.

9.1 Introduction
The AL2-ASI-BD connects onto the main unit of the α2 series controller, forming a slave
station for an AS-interface network (Input 4 points, Output 4 points). A maximum of 31 slaves
can be connected to form an AS-interface network. Power for the communication is supplied
over the AS-interface bus by the AS-interface power supply. The communication signal is
superimposed over the power supply on the AS-interface bus.
