Application areas for AS-Interface modules for front plate mounting
The AS-Interface modules for front plate mounting are used to connect an EMERGENCY
STOP device from the SIRIUS ACT series to the AS-Interface bus system according to ISO
13850. The modules for front plate mounting are suitable for pushbuttons with front plate
mounting.
The AS-Interface modules for front plate mounting have a safe AS-Interface slave 2I and are
snapped onto the holder from behind.
The expanded version 2I/1O includes an output for controlling a signaling element with LED.
Depending on the version, the connection to the AS-Interface bus cable is by means of
screw terminals, spring-loaded terminals or insulation displacement method. Addressing is
performed using the AS-Interface connection or the integrated addressing socket.
With the modules for front plate mounting, applications up to SILCL 3 as per IEC 62061, SIL
3 as per IEC 61508 and PL e (Cat. 4) as per ISO 13849-1 can be implemented depending
on the connection of evaluation device and actuators.
