The switch actuator REG-K/12x230/10 with manual mode (referred to below as the actuator) can switch
twelve loads via separate, floating make contacts. You can switch the actuator to manual operation and
check that it works even without ETS programming, and you can control the connected loads directly at the
actuator in the event of a bus failure. The actuator has a bus coupler. It is installed on a DIN
rail, with the bus connection made via a bus connecting terminal. A data rail is not required.
