ABB SA/S8.16.6.2 8-kertainen kytkinaktori 16A C-Load, DIN-kisko, KNX 2CDG110271R0011

Managing multiple lighting and load circuits in a KNX building automation system can become complex and space-consuming. The ABB SA/S8.16.6.2 switching actuator solves this by providing eight independent 16 A switching channels in a compact 4-module DIN rail housing. Each output uses a potential-free normally open contact, suitable for ohmic, inductive, and capacitive loads up to 140 µF, making it ideal for controlling lighting, HVAC, and other electrical loads in residential and commercial buildings.

Who is it for

This actuator is intended for system integrators, electricians, and building automation professionals who need a reliable, high-density switching solution for KNX installations. It is well-suited for projects where space in the distribution board is limited but many loads must be controlled individually.

Main features

• Eight independent switching outputs, each rated 16 A
• Supports ohmic, inductive, and capacitive loads (C-Load) up to 140 µF
• Compact DIN rail mounting, only 4 modules wide
• Manual operation via push buttons for testing and commissioning
• Status feedback via KNX bus for monitoring and logic functions
• Integrated functions: switching, scene control, time functions, central functions, and logic operations

Tips

When using the actuator with capacitive loads such as LED drivers or electronic ballasts, ensure the total inrush current does not exceed the rated 140 µF. For large installations, consider grouping multiple actuators on the same KNX line and using the built-in logic functions to reduce bus traffic.
