With the extension plug it is possible to double the cable length possible in an AS-Interface segment from 100 to 200 m.

Only one power supply unit is needed to supply power to the slaves on the up to 200 m long segment.

The Extension Plug Compact can be installed directly onto an AS-Interface shaped cable. In the case of the Extension Plug Compact version, there is no longer any need for a separate M12 branch such as the one needed for earlier versions of the extension plug.

Design of an AS-Interface segment with an extension plug

To construct an AS-Interface segment with a cable length of more than 100 m and up to a maximum of 200 m, the extension plug is installed in a radius of around В± 10 m at the point of the network that is furthest from the power supply unit. The extension plug is not allowed to be used in AS-Interface networks smaller than 100 m. As with all AS-Interface networks, any network structure (line, tree, star) is possible when using the extension plug. Only one extension plug is required per 200 m segment even with a tree or star structure.

Note:

The AS‑i bus must not terminate in the Extension Plug Compact. The AS‑Interface shaped cable may have to be terminated using the cable terminating piece to ensure IP67 degree of protection; see "Miscellaneous accessories".

The AS-Interface extension plug is not suitable for AS-i Power24V networks.
