3.4 AS-Interface Repeater / Extender
Area of Application
The AS interface repeater and extender is intended for use in an actuator-sensor
interface environment.
The device is used to extend the maximum possible length of the AS-interface of
100 m. An existing 100 m segment can be extended by a maximum of two further
100 m segments.
Using the Repeater
The AS-interface repeater is used when slaves must be operated on all cable
segments. A separate AS-interface power supply unit is then required for each
AS-interface segment (before and after the repeater). The repeater has the
following features:
S Extends the cable length to a maximum of 300m.
S Slaves can be used on both sides of the repeater.
S A power supply unit is required on both sides of the AS interface.
S Electrical isolation of the two cables.
S Separate indication of the correct voltage for each side.
S Installation in standard application module casing.
