Data and energy:
The primary switched mode DIN rail power supply SLA8.100 specifically
supplies AS Interface
logy allows to connect up to 62 participants to a control and to supply
them with energy with a single two-conductor cable. When connecting
slaves, the yellow AS-Interface cable offers the high degree of protection
IP67 in conjunction with the insulation displacement. The communication signals of the individual network participants are modulated onto
the supply voltage. For this purpose, specific power supply units with integrated data decoupling are required for AS-Interface systems.
Fast addressing of slaves:
The "IR addressing mode" selectable via jumper interrupts the data communication on the yellow AS-Interface cable. Participants with an infrared interface can then quickly be assigned a new ID address by means of
an infrared programming unit without the need to disconnect them
from the AS-Interface cable. Afterwards, the "Communication Mode"

can be selected again to re-start the data communication.
Safe operation by FUSE Mode:
The device features a FUSE Mode, which permanently switches off the
output in the event of failure and the unit at overload, short-circuit or
overtemperature and thus protects the relatively thin AS-Interface line
and the attached components. Triggering of the FUSE Mode is indicated
by a flashing LED. System restart requires the intentional activation of a
reset button on the front side of the unit. Thus, an accidental restart is
prevented and the slaves are protected against damage.
Fit for the world market:
The input voltage range of the unit can be selected on the front panel.
Thus, it can be operated worldwide on all usual single-phase line voltages. International (IEC 60950) and various national (CBscheme) approvals
allow for worldwide application.

FUSE Mode
The FUSE Mode (electronic fuse in the output) protects the unit from
overload and overtemperature.
Shutdown:
• At overtemperature, overload or short-circuit (8.4A < I
the unit switches off the output after 2...5s
Indicator:
• Activation of the FUSE Mode is indicated by a flashing red LED
Reset / Restart:
• by intentionally pushing the Reset button on the unit front panel
• by turning off the mains voltage. Before restarting the unit, wait at
least twice the time the flashing red LED needed to extinguish after
the mains voltage dropped.
