Function: VAR-G4F

The Advanced-Repeater VAR-G4F isolates two AS-Interface circuits galvanically from each other and processes the AS-Interface signals electrically, which extends the maximum line length by 100 m. Two Advanced-Repeaters can be connected in series resulting in a maximum line length of 300 m.

The Advanced-Repeater features an alignment between sender and receiver that has been optimized even further and offers a shorter delay when the signals pass through the Advanced-Repeater.

The Advanced-Repeater does not need any parameterization nor its own address on the AS-Interface; the total number of slaves (31 or 62) per line remains as it is.

A flat or round cable can be used for the connection to the AS-Interface transmission line. If the AS-Interface flat cable is to be used, the bottom part included in the scope of delivery is required. The contact to the two AS-Interface lines is made via the standardized EMS interface, i.e. by using the insulation penetration technique.

Due to the galvanic isolation, a power supply or power extender is required for each segment.

Two LEDs indicate the correct polarity of the AS-Interface lines, two LEDs signal communication faults in the respective AS-Interface circuits.
