Data and energy:

The primary switched mode DIN rail power supply SLA3.100 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 com-

munication 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.

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.
