AS-Interface Power Supply with 4A Data sheet Input: AC 115V / 230V Output: 30.5V / 4A AS Interface data decoupling Infrared (IR) addressing mode For highly demanding industrial applications • Ground Fault (GF) detector with signal output Short description Data and energy: The primary switched mode DIN rail power supply SLA4.100 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 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.

Data sheet Ground fault detector The ground fault detector monitors ground faults on the AS-lnterface 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. Incase 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-lnterface network must not contain any other ground fault detectors or insulation monitoring devices. LED 'Ground Fault (GF)' displays a current or stored ground fault push-button 'Reset/test'...

Data sheet Operating indicators and elements Plastic slider: • Mounting: Place the unit onto the DIN-rail and push it downwards and against the lower front edge until it snaps into place. • Detachment: Push downwards and detach the unit from its DIN-rail mounting bracket. Ground fault relay output: Closed: no ground fault Open: ground fault Green LED: ON: AS-Interface voltage is within the limits OFF: at overload or missing input voltage Plastic slider Output terminals: Dual terminals for AS-Interface + and AS-Interface – Machine ground connection Plug-in jumper: Pos. 1-2: regular AS-Interface...
