AS-Interface Power Supply with 8A Data sheet Input: AC 115V / 230V Output: 30.55V / 8A AS Interface data decoupling Infrared (IR) addressing mode Overload protection by FUSE Mode For highly demanding industrial applications Short description Data and energy: The primary switched mode DIN rail power supply SLA8.100 specifically supplies AS Interface® systems with energy. The AS-Interface bus technology 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.
