ABB Switch/Shutter Actuator, 8-fold, 6 A SAH/S8.6.7.1 KNX

Description

The compact 6 A combi switch actuator has 8 independent switching relays. The outputs can be used individually via ABB i-bus® KNX for switching electrical loads or in pairs for controlling 230 V AC roller shutter or blind drives (no electromechanically interlocking). The device features a manual operation, which can also be disabled. Via the manual operation the outputs can be operated manually and the switching or driving status is displayed. The device is powered by KNX and requires no additional power supply.

The device is a modular installation device (MDRC)
in proM design. It is designed for installation in
electrical distribution boards and small housings
with a 35 mm mounting rail (to EN 60715).
The device is KNX-certified and can be used as a
product in a KNX system → EU declaration of conformity.
The device is powered via the bus
(ABB i-bus® KNX) and requires no additional auxiliary voltage supply. The connection to the bus is
made via a bus connection terminal on the front of
the housing. The loads are connected to the outputs using screw terminals → terminal designation
on the housing.
The software application Engineering Tool Software (ETS) is used for physical address assignment and parameterization
