Repeater/Extender

■Benefits

Repeaters

•Expansion of the range of applications and greater freedom in plant design by extending the AS-Interface segment

•Reduction of standstill or service times in the event of a fault with separate display of the correct AS-Interface voltage for each end

Extenders

•Expansion of the range of applications and greater freedom in plant design by extending the AS-Interface segment

•When the extender is used, the master can be located at a distance of up to 100 m and a power supply is not required at the master end.

■Application

The repeater is used to extend the AS-Interface segment by 100 m.

The extender is used to extend the distance between the master and the AS-Interface segment with the AS-Interface slaves to a max. 100 m. A considerably greater cable length than 300 m can be achieved when the repeaters are connected in parallel.

The maximum extension range is 500 m.
