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-busÂ® 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.
