The GreenControls Switching Actuator, 4 Channel, 20A with Current Detection is a powerful KNX-certified device designed for switching and monitoring high-capacity electrical loads. Mounted on a 35mm DIN rail, it provides four independent outputs, each capable of handling up to 20A for resistive loads at 230VAC or 24VDC, making it ideal for lighting, HVAC, and other heavy-duty applications in residential, commercial, or industrial projects.
Beyond switching, this actuator features integrated current detection, enabling real-time monitoring of connected loads. This allows system integrators and facility managers to track consumption, optimize energy efficiency, and enhance fault detection across the installation.
Each output channel can be fully parameterized using ETS software to support switching, dimming, and scene control, providing flexibility for tailored automation scenarios. A mechanical bypass button is built into the device, allowing manual ON/OFF operation of each channel ensuring reliable functionality even if KNX communication is unavailable.
The actuator is equipped with LED indicators for quick diagnostics: a green LED confirms normal operation, while a red LED with push button is used for assigning physical addresses. Engineered for efficiency, it consumes less than 12mA from the KNX bus, with a maximum power draw of only 250mW.
Compact and durable, at 72 × 90 × 64 mm with a white finish, the actuator is fully EIB KNX certified and compliant with CE safety standards (EN 50090-2-2). With its combination of high switching capacity, current monitoring, and robust design, it is the ideal choice for projects that demand both performance and intelligent load management.
