• More possibilities of use and greater freedom for plant planning through extension of the AS-Interface network
• Reduced downtime and servicing times in the event of a fault thanks to separate display of the correct AS-Interface voltage for each side

Design of an AS‑Interface network with repeaters

• Parallel switching of several repeaters possible (star configuration)
• Combination of series and parallel switching possible

The following conditions apply:

• When used without an extension plug no more than two repeaters are permitted between AS‑i master and slave (repeaters connected in series).
• When used with an extension plug no more than one repeater is permitted between AS‑i master and slave.

In safety-related applications the following also applies:

• When used without an extension plug, no more than two repeaters are permitted between evaluation unit (e.g. MSS ASIsafe Modular Safety System, F‑CM AS‑i Safety ST for ET 200SP) and ASIsafe input slave or safe output module.
• When used with an extension plug, no more than one repeater is permitted between the evaluation unit (e.g. MSS ASIsafe Modular Safety System, F‑CM AS‑i Safety ST for ET 200SP) and ASIsafe input slave or safe output module.

Design of an example AS‑Interface network with repeaters (without extension plug)

Note:

The AS‑Interface repeater is not suitable for AS‑i Power24V networks. It is recommended for use in AS‑Interface networks with AS‑Interface power supply units (e.g. 3RX9501‑0BA00).
