Why Choose the ABB DW2 Digital Time Switch?
The ABB DW2 is a versatile two-channel digital weekly time switch designed for automatic control of lighting and other electrical loads according to programmed daily and weekly schedules. As part of the ABB DW digital time switch series, it combines flexible electronic scheduling with Bluetooth connectivity for convenient configuration in residential, commercial and industrial electrical installations.
The DW2 provides two independent switching channels, allowing separate electrical circuits or loads to be controlled from a single DIN-rail device. Up to 120 programme events can be stored, while standard, impulse, cycle, random and holiday functions provide flexibility for applications requiring precise and repeatable automatic switching.
Operating from a 230 V AC, 50/60 Hz supply, the DW2 features two change-over relay contacts with a maximum switching current of 16 A. Bluetooth communication enables programming and settings to be transferred using a compatible smartphone or tablet, while a replaceable backup battery preserves settings during interruptions to the mains supply.
