SK-RCU19S Dimming-Type Room Control Unit (RCU)

SK-RCU19S is a newly developed dimming-type Room Control Unit （RCU）host by our company, designed to accommodate a wider range of guest room lighting scenarios and effectively manage changes in light brightness and color temperature. The unit connects to external networks via 100M TCP, enabling integration with our cloud server platform for remote control, status synchronization, upgrades, configuration, and debugging. Using an RS485 bus, it facilitates communication within the room to coordinate the orderly operation of various devices. With supporting host computer software, room number and network settings can be configured conveniently and efficiently.

Commercial DIN-Rail RCU Controllers: Edge-Node Autonomy & Distributed Hospitality Intelligence

Empowering luxury hotels, resorts, and smart healthcare facilities with localized edge computing, high-inrush magnetic latching relays, and native multi-bus protocol bridges. Engineered for 100% offline operational resilience and up to 30% HVAC energy reduction.

Autonomous Edge-Computing Logic & 100% Offline Operational Resilience

Every SOUKA Room Control Unit (RCU) runs dedicated localized edge firmware. All in-room interactions—including wall switch presses, multi-scene lighting loops, motorized curtains, and thermostat controls—execute locally within the physical RCU hardware with sub-50ms response latency. Even during building-wide LAN disconnects, IoT server downtime, or cloud dropouts, in-room environmental controls remain 100% functional and offline-autonomous.

16A / 30A Magnetic Latching Relays & Zero-Cross Inrush Current Suppression

Engineered to withstand the extreme inrush currents of modern commercial LED lighting, SOUKA RCUs integrate industrial-grade 16A / 30A magnetic latching relays with hardware-level zero-cross switching detection. This technology clamps capacitive inrush spikes (up to 500A/2ms) at the zero-voltage AC crossing point, completely eliminating contact welding, minimizing heat dissipation, and guaranteeing over 100,000 heavy-duty switching cycles.

Native Multi-Bus Interoperability (RS-485 / KNX / Modbus) & 0-10V/DALI-2 Dimming

SOUKA RCUs provide native hardware ports for industrial fieldbuses—including optically isolated RS-485, Modbus-RTU, and KNX—alongside optional Zigbee 3.0 wireless mesh. The controller integrates multi-channel 0-10V, DALI-2, and Trailing-Edge Phase-Cut dimming loops alongside Modbus/0-10V HVAC proportional valves. Paired with real-time mmWave presence radar telemetry, it automates temperature setbacks in empty rooms, cutting property HVAC energy waste by up to 30%.
