General information

3 General information
The Actuator Sensor Interface (AS-Interface) is established as a system
for networking primarily binary sensors and actuators on the lowest level
of the automation hierarchy. The high number of installed systems, simple
handling and the reliable operating behaviour make AS-Interface
promising for the area of machine safety as well.
System features
When used according to the intended purpose in combination with an
appropriately programmed AS-Interface Safety at Work safety monitor,
the AS-Interface safety slave described here makes it possible to operate
sensorcontrolled personal protection equipment up through Category 4 in
accordance with EN 954-1.
The safety monitor must be sufficient for the requirements of the system
specification "Specification of secure AS-Interface transfer" Version 2.01
dated May 12, 2000.
The slave is equipped with two safety-related inputs. A mechanical switch
in accordance with EN/IEC 60947-5-1 or a proximity switch of
Pepperl+Fuchs with defined behavior in case of a failure in accordance
with the SN/S1N Specification and EN/IEC 60947-5-3, Type S
(corresponding to Category 3 in accordance with EN 954-1/ISO 13849-1)
can be connected to each of these.
