Function: VAN-G4-PE-4A

The maximum cable length in an AS-Interface line is 100 m. There is often a great distance to the modules in the field, when the power supply unit is located in the cabinet. When an AS-Interface power extender is used, the distance between the power supply unit and the power extender is not included in the calculation of the bus length. Instead of an AS-Interface power supply unit, a standard power supply unit with an output voltage of 30 V in accordance with AS-Interface specifications can be used. The AS-Interface master and slaves are only usable on the side of the power extender opposite to the power supply unit (AS-Interface output).

The AS-Interface power extender is located in an IP67 rated field housing. Small decentralized AS-Interface networks can easily be arranged together with IP67 rated AS-Interface gateways.

Depending on the lead resistance and the current, a voltage drop between the power supply unit and the AS-Interface power extender occurs. The AS-Interface power extender indicates the AS-Interface voltage on the output, in two stages (see technical data) by means of two LEDs. It has to be ensured that actuators are supplied with the permissible voltage tolerance of 24 V +10%/-15%, as is the case with all AS-Interface circuits. A ruleof- thumb formula for the AS-Interface cable length relative to the AS-Interface voltage is:

  • AS-Interface voltage > 28 V: approx. 80 m cable length,

  • AS-Interface voltage > 26 V: approx. 60 m cable length.


The AS-Interface power extender contains a data decoupling for a maximum current of 4 A at 30 V AS-Interface voltage.
