Technical data
The electronic switch actuator is a modular
DIN-rail component for contactless switching
of resistive loads. It is used mainly to control
heating systems and cooling ceilings via
electro-thermal valve-drives.
The electronic switch actuator is designed for
DIN-rail installation in electrical distribution
boards or in heating system distribution boards.
The device can be operated with DC or AC
voltage (24 V ... 230 V AC/DC) and offers 4
potentially bound outputs which switch silently
and wear-free.
Device power supply via ABB i-bus EIB
Power input 24 V ... 230 V AC/DC
