System configuration with optional AS-i mounting module
The compact starter with 24 V control voltage can be controlled via an AS-Interface. The
actuator sensor interface (AS-Interface) is a modular networking system for sensors and
actuators at the lowest field level.
Configuration
If the AS-Interface is being used for control purposes, the AS-i mounting module needs to be
installed on the compact starter (24 V) instead of the two auxiliary circuit terminals. The AS-i
and auxiliary voltage cables are connected to the AS-i mounting module.
An AS-i power supply is used to feed the AS-i voltage into the AS-i cable, which also serves
as a communication cable between the AS-i master and slave. The auxiliary voltage is
supplied by a 24 VDC PELV power supply in accordance with VDE 0106 safety class III.
For additional information on the AS-Interface, please refer to the manual entitled
"AS-Interface System"
(order number: 3RK2703-3AB02-1AA1).
For additional information on connecting the AS-i mounting module, please refer
to "Connecting the compact starter (24 V) with optional AS-i mounting module (Page 77) ".
