AS INTERFACE - DESIGN

12.1. Defini on
AS interface connec on
AS interface (Actuator Sensor Interface) is a field bus system which is used primarily for networking binary sensors and actuators
(slaves) with a higher-level controller (master).
Connec)ng the control heads to higher bus systems is possible using commercially available gateways.

Contact your customer services representa)ve for more informa)on.
Bus line:
Power and data transmiVed on a two-wire unshielded cable
Network topology:
Freely selectable within wide limits. AS-interface can use star or dropline topology or a mixture of both. Bus length limits depend
on the equipment employed, but the nominal limit of 100m* can be increased if using ac)ve bus termina)on and bus repeaters.
The F783E control head module for AS-i uses extended addressing to achieve 62 slaves (A/B addressing) and is designed to be
compa)ble with the AS-i specifica)on 3.0, and is fully backward compa)ble to AS-i 2.1. it can op)onally programmed to operate
with standard addressing for 31 slaves.
* NOTE!
•
Maximum supply cable length is to be 30m. Control top must be installed in the same building as the control cabinet.
•
Installa on environment and wiring are influen al on the module's EMC: Thus the installer must secure EMC of the
whole device.
•
According to Norm EN 61326-1: 2006 (chart 2) DC supply connec ons to the module are treated as input/output
signal lines. For cable lengths greater than 30 m and outdoor applica ons addi onal measures must be implemented
in order to comply with CE
