Kytkin-/kaihdinaktuaattori ABB REG SAH/S24.16.7.1 24‑kanava 16 A (2CDG110252R0011)

ABB REG SAH/S24.16.7.1 is a 24‑channel switch and shutter actuator designed for KNX automation installations. Each channel provides a 16 A switching capacity, enabling centralized control of lighting circuits and motorized blinds or shutters within residential and commercial projects. The device supports grouped switching and simplifies wiring by concentrating multiple outputs into a single DIN-rail mounted module suitable for electrical distribution panels.

Advantages

The actuator combines high channel density with robust 16 A switching on each output, reducing the need for multiple separate relays. Its compatibility with KNX systems allows for flexible scene control, timed operations and integration with other building automation functions. The compact DIN-rail form factor saves panel space while delivering reliable load handling for common lighting and shutter motor types.

Suitable for

• Centralized control of lighting circuits in apartments, houses or office spaces
• Operation of motorized blinds, shutters and sun protection systems
• Grouped switching and scene control in KNX smart home or building automation projects
• Electrical distribution panels where space-efficient multi-channel switching is required

Key specifications

• Number of channels: 24 independent switching outputs
• Switching capacity: 16 ampere per channel
• Intended application: switch actuator for lighting and shutter/motor control in KNX systems
• Mounting: DIN-rail mounting for electrical distribution cabinets
• Control interface: KNX bus integration for group addressing, scenes and timed controls
• Load types: designed for resistive and inductive loads typical for lamps and shutter motors

How to use

Install the actuator on a standard DIN rail inside the distribution cabinet and connect the KNX bus for communication and power. Wire each load to the corresponding channel output and ensure protective devices such as circuit breakers are fitted according to local electrical codes. Configure channels and group addresses using KNX engineering software to define switching logic, scenes and timed operations. Verify correct operation of shutters or motors by testing end limits and control commands after commissioning.

Recommendations

Use appropriate circuit protection and cable sizing for 16 A outputs, and ensure motor end stops and thermal protection are in place for shutter motors. For reliable operation, follow KNX commissioning procedures, update device parameters as needed, and avoid exceeding rated load per channel.
