Functions
Application
The primary switch mode power supply is specifically designed with integrated data decoupling for the supply of AS-
interface systems. It operates at two selectable input voltage ranges and can be used worldwide, within compact
dimensions. The easy-to-set front-face jumper allows the assignment of new ID addresses to slaves by means of an
external infrared programming unit without disconnecting them from the AS-Interface cable.
Up to 62 binary I/O devices can be connected and supplied according to the AS-interface bus technology with a single
two-conductor cable. The communication signals are modulated onto the slaves' DC supply voltage of the AS-interface
system, which therefore requires a specific power supply with integrated data decoupling.
Operating mode
By means of the input voltage selector the input voltage can either be set to 115 V AC or 230 V AC. The front-face
jumper allows the configuration of the operation mode of the power supply, i.e. "1-2 COMMUNICATION MODE" or "2-3
IR ADDRESSING MODE" to enable communication control and supply of AS-interface slaves or to interrupt the data
communication for the assignment of new ID addresses to participants by means of an external infrared programming unit.
The green LED "AS-I OK" is on during normal operation, i.e. when the output voltage exceeds 30 V DC, and is off at
overload.
The red LED "IR ADDRESSING ON" is on when data communication has been interrupted by means of the jumper.
