AS 235 H extension cabinet
Depending on the complexity of the automation function, the
AS 235 H can be increased up to max. 91 slots for I/O modules
by using up to 7 extension units.
The extension units EE4 to EE7 are part of the extension cabinet.
They are connected to the central processing unit of an
AS 235 H system via 2 separate, redundant I/O buses 2 (B),
each with its own interface module for I/O bus (B).
An extension unit of the AS 235 H automation system consists of
a subrack with slots for 13 I/O modules, I/O bus comparator and
switchover module, and a DC 5 V power supply module.
When ordering the extension units it is possible to select whether
the extension unit EE4 is to be delivered on its own, together with
EE5, together with EE5, or together with EE6:
