Use AS-Interface power supplies only together with AS-Interface lines.

Data and energy:

The primary switched mode DIN rail power supply SLA4.100 specifically

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 communica-

tion signals of the individual network participants are modulated onto

the supply voltage. For this purpose, specific power supply units with in-

tegrated data decoupling are required for AS-Interface systems.

Fast addressing of slaves:

The "IR addressing mode" selectable via jumper interrupts the data com-

munication on the yellow AS-Interface cable. Participants with an infra-

red 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 oper-

ated on all usual single-phase line voltages. Its design corresponds to in-

ternational 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 mod-

ules redundant. The AS-Interface network is monitored by the power

supply unit via the AS-Interface cable connected to the various partici-

pants. 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.
