Function

The Advanced-Repeater VAR-KE3-TERM galvanically separates two AS-Interface circuits, and conditions the AS-Interface signals electrically, which extends the cable length by 100 m. The Advanced-Repeater includes a Bus Termination, permitting a line extension of up to 200 m. The Bus Termination is switchable. Two repeaters can be cascaded, resulting in a maximum cable length of 300 m. With one Bus Termination included in line, the maximum circuit extension is up to approximately 600 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 require any parameterisation and no own address in the AS-Interface; the overall number of slaves (31 or 62) per branch remains unchanged.

The housing, only 22.5 mm in width, takes up little place in the switch cabinet. The module is mounted by snapping it on to the 35 mm mounting rail in keeping with European standard EN 50022. Pluggable screw terminals are used for connection. This method of mounting permits easy removal during initial operation or servicing.

On account of the galvanic separation, each segment requires a power supply unit or a power extender.

Two LEDs indicate the correct polarity of the AS-Interface cables; two LEDs indicate any communication errors in the respective AS-Interface circuits.
