4.5.2 Features and technical data
The device can be directly integrated in an AS interface network is parametrised in its factory settings
so that the most frequently used AS-i functionality is available immediately. Only adaptations for
application-specific functions of the device or the bus system, the addressing and proper connection of
the supply, BUS, sensor and actuator cables need to be carried out.

Features
• Electrically isolated bus interface
• Status display (LED)
• Configuration by parameterisation
• 24 V DC supply (integrated AS-i module and Frequency Inverter)
The following possibilities should be applied.
a. Device with integrated power supply unit (device option “ -HVS ”) and connector option “ -ASI ” or
“ -ASS ”
– Connection via yellow cable for the supply of the AS-i module
– Supply of the device and connected initiators or actuators via an integrated power supply
unit
Note: If no mains voltage is present on the device, connected initiators are not visible for the
AS-i master.
b. Device with integrated power supply unit (device option “ -HVS ”) and connector option “ -AUX ” or
“ -AXS ”
– Connection via yellow cable for the supply of the AS-i module
– Connection via black cable for the supply of the device and the connected initiators
Note: If the black cable’s voltage falls below the voltage of the integrated power supply unit,
the power supply unit takes over the device supply. If the black cable’s voltage falls below
approx. 16 V DC, the integrated power supply unit also takes over the supply of the
connected initiators or actuators.
c. Device without power supply unit (without device option “ -HVS ”) and with connector option “ -
AUX ” or “ -AXS ”
– Connection via yellow cable for the supply of the AS-i module
– Connection via black cable for the supply of the device and the connected initiators or
actuators
d. Device without power supply unit (without device option “ -HVS ”) and with connector option
“ -ASI ” or “ -ASS ”
– Connection via yellow cable for the supply of the AS-i module and the device
Note: This version causes a high current consumption for the AS-i cable and only offers low
reserves for direct connection of initiators and actuators to the device.
• Connection to the device
– Via M12 system plug connector at option slot M8
