Core Technical Parameters

• Basic Specification: Model SA/S 2.6.2.1, belonging to ABB MDRC professional actuator series, is an industrial-grade small switch actuator integrated with "automatic + manual dual control mode". Its core differential advantage is supporting on-site manual emergency operation, designed specifically for small electrical loads and scenarios requiring emergency management and control, and is a core executive device for local control of building automation.
• Rated Load: 6 A AC switching capacity, suitable for on-off control of low-power electrical loads. The load type is compatible with resistive, inductive and small capacitive loads (such as small LED lights, micro fans, mini exhaust fans, small display lights, etc.), accurately meeting the control needs of small areas and local points, with low power consumption and strong adaptability.
• Core Function (Manual Operation): Supports on-site manual start-stop operation, equipped with independent manual buttons/dip switches, no need to rely on the building central control system — even if the central control system is powered off, faulty or under commissioning, the load can be emergency switched directly through manual operation, greatly improving the reliability and emergency response efficiency of equipment operation. Automatic and manual modes can be seamlessly switched without affecting normal intelligent linkage.
• Communication & Compatibility: Compatible with ABB building automation control system, supporting KNX/EIB intelligent building control bus (mainstream industry protocol), which can be integrated into the intelligent building linkage system to realize flexible switching between remote monitoring, centralized control and on-site manual operation; compact size, suitable for installation in small distribution boxes and control boxes, with simple wiring, convenient commissioning and later maintenance, no need for professional and complex operations.
• Product Attributes: Designed to industrial-grade standards, it has the characteristics of anti-electromagnetic interference, temperature resistance (-10℃~50℃) and moisture resistance, and can stably work in various indoor small control scenarios (such as stores, classrooms, corridors, etc.); the shell is made of flame-retardant material, built-in dual protection of overload and short circuit, effectively avoiding equipment damage caused by abnormal loads, extending the service life of products and controlled loads, and adapting to long-term continuous operation needs.

2. Core Application Scenarios

• Small Commercial Scenarios: Control of local lighting, micro exhaust fans, display lights and cash register auxiliary lights in convenience stores, community shops, small flower shops and milk tea shops. Manual operation can meet the on-site immediate switch and emergency commissioning needs of clerks, and automatic mode can adapt to simple intelligent linkage (such as timing switch).
• Industrial Building Auxiliary Areas: Control of local auxiliary lighting in workshops, micro cooling fans in computer rooms, ventilation equipment in warehouse corners, and small indicator lights on production lines of standard factories. When the central control system fails, manual operation can ensure the normal operation of auxiliary equipment, avoiding affecting production progress.
• Public & Civil Local Areas: Control of local lighting in school classrooms, hospital consulting rooms, community corridors and elevators; control of small landscape lights in parks, door lights of community units and corridor guide lights. Manual operation is convenient for managers to conduct on-site commissioning and emergency shutdown, adapting to the convenient management and energy-saving needs of public areas.
• Small Residences & Supporting Facilities: Control of local lighting in studies, balconies and cloakrooms of mid-to-high-end apartments and villas; control of small smart home auxiliary equipment (micro fresh air fans, mini dehumidifiers). Manual operation meets the on-site immediate control needs of residents, and automatic mode can be integrated into the whole-house intelligent system to realize linkage switching, taking into account convenience and flexibility.
