SA/S 2.16.2.1 ABB Industrial Switch Actuator 16 A MDRC Series Building Automation

. Core Technical Parameters

1. Basic Specification: Model SA/S 2.16.2.1, belonging to the ABB MDRC professional actuator series, is an industrial-grade switch actuator dedicated to building automation. As a core executive device for medium and high-power load control in intelligent buildings, it is suitable for the load management needs of the whole of small and medium-sized buildings or partitions of large buildings.
2. Rated Load: 16 A AC switching capacity with wide load adaptability, compatible with resistive, inductive and small-to-medium capacitive loads (such as high-power lighting, medium fans, small HVAC water pumps, etc.). Compared with the 10 AX model of the same series, its load driving capacity is improved, and it can directly connect to medium-power building electrical equipment.
3. Communication & Compatibility: Fully compatible with ABB's own building automation control system, natively supporting the KNX/EIB intelligent building control bus (the mainstream industry protocol). It can realize three modes: centralized control, distributed control and remote linkage, adapting to the standardized wiring and commissioning of intelligent buildings. It can seamlessly connect with the building central control system, feed back the load operation status in real time, and support multi-device linkage programming.
4. Product Attributes: Adopting industrial-grade design standards, it has the characteristics of anti-electromagnetic interference, temperature resistance (-10℃~50℃) and moisture resistance, and can stably work in complex electrical environments such as building distribution boxes and control boxes. With a compact size, it fits the standardized installation layout of building automation equipment, supports 24-hour continuous and stable operation, and is convenient for disassembly, debugging and maintenance in the later stage.
5. Core Features: Built-in dual electrical protection of overload and short circuit, which effectively avoids damage to equipment caused by abnormal loads and voltage fluctuations, and prolongs the service life of products and controlled loads. It is adapted to wide voltage input, compatible with the building power grid standards in different regions, with strong versatility and no need for additional adaptive accessories.

2. Core Application Scenarios

1. Commercial Buildings: Start-stop and linkage control of large-area public area lighting, high-power ventilation and smoke exhaust fans, high-power window display cabinets, and small circulating water pumps in HVAC systems in office buildings, small and medium shopping malls, and business hotels, adapting to the needs of intelligent energy saving and convenient management in commercial scenarios.
2. Industrial Buildings: On-off control of workshop main lighting, medium cooling fans in computer rooms, medium-power power circuits in production auxiliary areas, and high-power lighting in storage areas in standard factories, R&D workshops and small data centers, taking into account the stability and anti-interference requirements of industrial scenarios.
3. Public and Civil Buildings: Control of main lighting in public areas, small water supply and drainage pumps, and high-power guide lights in passages in primary and secondary schools, community hospitals and cultural venues; control of medium-power circuits for landscape lighting and power supply of park public facilities in urban parks and small cultural tourism scenic spots, adapting to the all-weather operation needs of public areas.
4. Smart Parks & Residences: Control of road lighting and medium-sized public facilities (such as automatic irrigation, small monitoring equipment) in smart industrial parks; centralized linkage control of underground garage lighting/exhaust equipment in mid-to-high-end commercial and residential complexes, and whole-house high-power lighting + fresh air systems in high-end apartments.
