■ Overview
AS-Interface power supplies are an essential and functionally
important part of an AS-Interface network. They supply the elec-
tronics of the network (AS-Interface modules and AS-Interface
masters) and the connected sensor technology. Furthermore,
the integrated data decoupling of AS-Interface power supplies
ensures the separation of data and energy, thus enabling AS-
Interface to transmit data and power on a single cable.
■ Benefits
• Compact dimensions save space in control cabinets or
in the field
• Higher output rating enables connection of even more
AS-Interface nodes
• Integrated ground-fault and overload detection ensure that
applications are more reliable and save the need for additional
components
• Diagnostics memory, remote indication and remote reset allow
fast detection of faults in the system, thus reducing downtimes
• Fast and stable installation of devices thanks to spring-type
connections
• Removable terminal blocks allow fast component replace-
ment, thus reducing downtimes
• The ultra-wide input range of the 8 A version permits single-
phase and 2-phase operation - so there is no need for connec-
tion of an N conductor
• UL/CSA approval means the power supplies can be used
worldwide
The 2.6 A version is approved according to NEC Class 2.
■ Application
AS-Interface power supplies are always used in conjunction with
AS-Interface networks.
