1. INTRODUCTION
The AL-ASI-BD and AL2-ASI-BD Actuator Sensor Interface board module (Hereafter referred to as the
AL-ASI-BD) is used in conjunction with the following
communication over an Actuator Sensor Interface (AS-interface) network.

Model Name of Interface
AL-ASI-BD
AL2-ASI-BD
The AL-ASI-BD connects onto the main body of the
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.
