PULS SLA8.300 INTRODUCTION
The primary switched-mode DIN rail power supply SLA8.300 specifically
supplies AS Interface® systems with energy. The AS-Interface bus
technology allows connecting up to 62 participants to a control and supplying them with energy with a single two-conductor cable. When
connecting slaves, the yellow AS-Interface cable offers a 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 ASInterface 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 using an infrared programming unit without the need to disconnect them from the AS-Interface cable. Afterward, the "Communication Mode" can be selected again to restart 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.
