Description
Security Terminal, 8-fold
The Room Controller Basis Device
RC/A 4.2 can accept up to 4 plug-in
modules. It controls their function and
communicates as a bus device via
the ABB i-bus® KNX.
Any module type can be plugged into
every module slot.
The inserted module is detected automatically
and linked with the internal
supply voltage and incoming mains
supply if necessary.
The mains supply is connected to the
device using a single phase (L, N and
PE).
The manual operation facility enables
an immediate function test even when
bus voltage is not applied.
