The ABB SAH/S16.6.7.1 KNX Switch/Shutter Actuator is a compact combi switch/shutter actuator for ABB i-bus® KNX building automation. A single DIN-rail module delivers 16 independent relay outputs at 6 A per channel, balancing channel density and panel footprint for mid-size commercial and residential distribution boards.
Install on standard 35 mm DIN rail (MDRC). The actuator is powered entirely from the KNX bus (TP) — no auxiliary supply — which simplifies wiring and reduces component count in the cabinet.
Key Features and Technical Highlights
The SAH/S16.6.7.1 combines flexible output mapping with proven SAH/S combi functionality, so integrators can mix switching and shutter control without adding extra hardware.
High-Density, Versatile Outputs
- 16 independent outputs: Electromechanical relays for up to 16 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 of lighting circuits, socket outlets, ventilation, or pumps — or pair them (8 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 16 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: 10 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 5 W — factor into KNX power supply sizing on lines with many bus-powered devices.

Applications and KNX Integration
When panel space matters but a full 24-channel module is not required, the SAH/S16.6.7.1 offers a practical mid-density option for floor or wing-level control.
- Commercial and institutional: Centralized lighting and blinds from one MDRC position — suitable for small offices, classrooms, hotel floors, and healthcare zones.
- Residential: One module can serve multiple rooms, reducing cabinet depth and cable routing complexity in smart-home panels.
- ETS configuration: Import the official .knxprod application (see Downloads), assign group addresses, scenes, schedules, central commands, and priority logic alongside ABB KNX sensors, push buttons, and visualisation.
- Project documentation: Data sheet, connection diagram, dimensional drawing, CAD, EPLAN, specification text, and installation manual are available under Downloads for planning and tender specifications.
Choosing Channel Count in the SAH/S 6 A Series
ABB offers the same 6 A combi platform at 8-fold (SAH/S8.6.7.1), 16-fold (this model), and 24-fold (SAH/S24.6.7.1). Select SAH/S16.6.7.1 when a single module must handle a moderate number of circuits without occupying a full 12M width. Step up to SAH/S24.6.7.1 for maximum density; choose SAH/S8.6.7.1 for compact panels with fewer loads.
