The ABB SA/S12.10.2.2 KNX Switch Actuator is a next-generation standard switch actuator for ABB i-bus® KNX. It provides 12 independent potential-free relay outputs at 10 A per channel, making it ideal for high-density switching of lighting, ventilation, and other resistive or slightly inductive loads in commercial and residential projects.

The device is especially suited for loads with high inrush currents — for example fluorescent and similar luminaires per EN 60669 — while remaining fully KNX bus-powered with no auxiliary supply. Manual operation with ON/OFF status indication supports commissioning and maintenance.

Key Features and Technical Highlights

Part of ABB's unified Standard Switch Actuator range with tool-free DIN-rail mounting and ETS App Update Copy Convert support.

High-Density Switching Outputs

• 12 independent outputs: Potential-free contacts for up to 12 separate 230 V AC loads.
• 10 A rated current: Up to 2500 W switching power per output (AC-1 — non-inductive or slightly inductive loads).
• High surge capability: Designed for fluorescent and similar loads with elevated inrush; not suitable for C-load capacitive switching.
• Contact feedback: ON/OFF contact position indication on the device.

Control, Commissioning, and Reliability

• Manual operation: Local override on the module; status visible without bus voltage for selected diagnostics.
• Bus-powered: No separate 230 V or 24 V supply for KNX electronics.
• ETS configuration: Import the official .knxprod application; template pages and central functions simplify multi-output programming.
• Load shedding: Integrate outputs into energy or load-management logic (parameter-dependent).
• ABB EcoSolutions: Documented recyclability and circular design principles (see Technical Specifications).

Standard vs Combi Actuators

SA/S12.10.2.2 is a dedicated switching actuator (12 × ON/OFF). For combined lighting and shutter control in one module, see ABB SAH/S combi actuators. For 24-channel density with shutter pairing, consider SAH/S24.6.7.1 and SAH/S24.10.7.1.
