ABB SA/S4.10.2.2 KNX kytkinaktuaattori, 4-kanava, 10 A, DIN-kisko 2CDG110258R0011

The ABB SA/S4.10.2.2 is a KNX switching actuator with four independent channels, each rated at 10 A for switching resistive, inductive, and capacitive loads up to 230 V AC. It is designed for DIN rail mounting in electrical distribution boards and integrates directly into KNX bus systems for intelligent building control.

Advantages

Each channel can be manually operated via push buttons on the device, allowing direct testing and commissioning without bus communication. The actuator supports logic functions and status feedback, enabling flexible automation scenarios. Its compact 4-module width saves space in distribution boards.

Suitable for

• Switching lighting circuits in residential and commercial buildings
• Controlling heating valves, fans, and other electrical loads
• Integrating with KNX building management systems
