1. INTRODUCTION
The AL-ASI-BD Actuator Sensor Interface board module (Hereafter referred to as the AL-ASI-BD) is used
in conjunction with an AL-20MR-A, AL-20MR-D or AL-20MT-D
over an Actuator Sensor interface (AS-Interface) network.
The AL-ASI-BD connects onto the main body of the
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.
