Data and energy:
The primary switched mode DIN rail power supply SLA4.100 specifically
supplies AS Interface
nology 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 restart the data communication.

Worldwide operation:
This compact primary switched-mode built-in power supply can be operated on all usual single-phase line voltages. Its design corresponds to international standards. The CE-Declaration allows for industrial and office
application.
Ground fault detector:
Acc. to EN60204 part 1 and DIN VDE0113 respectively, ground faults in
control circuits must neither cause a machine to start inadvertently or to
dangereously move nor prevent a controlled shutdown. The internal
SLA4 ground fault dectector makes external ground fault detector modules redundant. The AS-Interface network is monitored by the power
supply unit via the AS-Interface cable connected to the various participants. Detected ground faults are stored and signalled via front panel
LEDs and relay contacts. The ground fault detector may be manually
checked using the test/reset button.

Ground fault detector
The ground fault detector monitors ground faults on the AS-Interface
lines and includes a self-test feature. The ground fault feature consists
of the LED 'Ground Fault (GF)', a 'Test/Reset' push-button and a relay
output. In case of failure, the output voltage will not switch off. For
proper functioning, it is essential to connect the shield terminal to PE
or machine ground. The AS-Interface network must not contain any
other ground fault detectors or insulation monitoring devices.

Installation notes
External fusing • not necessary (internal fuse)
Mounting position vertical; input below, output above
Free space for cooling above / below 25mm recommended
Always connect PE before operating the unit!
Operation without AS-Interface: This AS-Interface PSU has an inductive output. When operating without AS-Interface structure (e.g. in
a laboratory test) you should connect a 470µF / 35V capacitor between
AS-Interface + and AS-Interface – as commercial electronic loads in
combination with the data decoupling often tend to oscillate, and the
oscillation may exceed the permitted modulation voltage. Otherwise,
equipment may be destroyed.
