ABB Low Voltage Controls

The CP-ASI power supply range is specifically designed with integrated data decoupling for the supply of AS-Interface systems. Up to 62 slaves (binary I/O devices) can be supplied with a single two-conductor cable. The configurable IR addressing mode allows the easy assign of new ID addresses by means of an external infrared programming unit.

CP-ASI/4.0 Range

The primary switch mode power supply is specifically designed with integrated data decoupling for the supply of AS-interface systems. To ensure a safe supply acc. to EN 60204 part 1 and DIN VDE 0113, an integrated ground fault detector monitors the AS-interface system to prevent a machine to start inadvertently, dangereously move or to shutdown.

The power supply 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.

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 ADRESSING MODE" to either control and supply AS-interface slaves or to interrupt the data communication for the assignment of new ID addresses to slaves by means of an external infrared programming unit.

Detected ground faults are stored and signalled. The front-face "TEST/RESET" button activates the ground fault test function or resets the internal fault storage. For proper functioning, it is essential to connect the shield terminal to PE or machine ground. The AS-interface network must not contain any other ground fault detectors or insulation monitoring devices.

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.

The red LED "GROUND FAULT" is on when a ground fault is present or has been stored.

Datalogic Sensors

The Emission is infrared LED with a narrow light beam, allowing resolutions up to 0.5 mm. All models, characterized by a compact metallic housing and by a M5 threaded hole, a ø5x8 slotted hole, and the dovetail guide are universal mountable. 2 m cable or M8 4-pole connector versions are available, and with NPN or PNP outputs. The slot photoelectric sensors of the SR23 series, with 50x5 mm slot size, are designed for the detection of normal labels,

IDEC Power Supply

The PS3L series replaces the PSR, PS3E and PS3C series IDEC power supplies. PS3L series features a sturdy metal frame and a form factor that requires less panel space than the IDEC PS5R series power supplies. PS3L series is finger-safe with output capacities ranging from 10W to 300W with 5V, 12V and 24VDC versions. A variety of mounting brackets allow for DIN rail mounting or several orientations of direct surface mounting.
