The ABB SAH/S8.6.7.1 KNX Switch/Shutter Actuator is the most compact 6 A combi switch/shutter actuator in the ABB SAH/S range. A single 4-module MDRC device delivers 8 independent relay outputs on 230 V AC, ideal for apartment panels, small commercial zones, and extension boards where every millimetre of DIN-rail space counts.
Install on standard 35 mm DIN rail (MDRC). The actuator is powered entirely from the KNX bus (TP) — no auxiliary supply — which keeps wiring simple in tight distribution cabinets.
Key Features and Technical Highlights
The SAH/S8.6.7.1 offers the same proven combi logic as larger SAH/S modules in a half-width footprint, making it a cost-effective entry point for mixed lighting and shading control.
Compact, Versatile Outputs
- 8 independent outputs: Electromechanical relays for up to 8 separate electrical loads on 230 V AC.
- 6 A rated current: Up to 1200 W switching power per output (AC-1 — resistive or slightly inductive loads; not suitable for C-load capacitive switching).
- Combi functionality: Use outputs individually for ON/OFF switching — or pair them (4 shutter channels) for 230 V AC roller shutter and blind drives without electromechanical interlocking.
- Flexible mapping: Any combination of single-switch and paired shutter channels within the 8 outputs.
Control, Diagnostics, and Reliability
- Manual operation: Local override buttons on the device; central disable or lock via KNX for maintenance or security.
- Status indication: 8 LEDs plus contact position feedback (ON/OFF) for clear field diagnostics.
- Bus-powered: No separate 230 V or 24 V auxiliary required for the KNX electronics.
- Power loss: Approximately 2.5 W — the lowest in the SAH/S 6 A family, helpful on KNX lines with limited bus power.

Applications and KNX Integration
The SAH/S8.6.7.1 suits projects where a handful of circuits — not an entire floor — need centralized KNX control from one actuator position.
- Residential: Lighting and blinds for multiple rooms in a single apartment or villa distribution board.
- Small commercial: Meeting rooms, retail units, and back-of-house areas with limited circuit count.
- ETS configuration: Import the official .knxprod application (see Downloads), assign group addresses, scenes, schedules, and central commands alongside other ABB i-bus® KNX devices.
- Project documentation: Data sheet, connection diagram, dimensional drawing, CAD, EPLAN, specification text, and installation manual are available under Downloads.
Choosing Channel Count in the SAH/S 6 A Series
ABB offers the same 6 A combi platform at 8-fold (this model), 16-fold (SAH/S16.6.7.1), and 24-fold (SAH/S24.6.7.1). Select SAH/S8.6.7.1 for compact panels with up to eight switching channels or four shutter pairs. Step up to SAH/S16.6.7.1 or SAH/S24.6.7.1 when higher channel density is required in the same cabinet.
