The ABB LR/S 4.16.1 is a high-performance 4-channel KNX light controller with MDRC functionality, engineered for intelligent, centralized control of commercial and industrial lighting systems. Specialized in 1-10V dimming control for electronic ballast-equipped luminaires, it delivers 16A high-load switching capacity per channel and core constant light control—enabling daylight harvesting when paired with dedicated light sensors for energy efficiency and optimal lighting comfort. As a master device for ABB i-bus® systems, it supports independent programming for each channel (switching, dimming, scene recall, staircase lighting) and seamless integration with other KNX actuators/gateways. With bus-independent manual on-device operation and a compact DIN-rail design, it offers reliable, flexible control for multi-zone lighting scenarios, balancing high performance with easy installation and on-site maintenance.
DIN-rail mounted (8 division units, 35mm standard DIN rail)
Operating Voltage
110-230V AC (50/60 Hz) - wide voltage compatibility
Protection Class
IP20 (indoor cabinet installation)
Operating Temperature
-5°C to +45°C (no condensation)
Certifications
CE, KNX BTL certified, RoHS compliant
Housing Design
Flame-retardant plastic, compact industrial-grade construction
Application Scenarios
Large Commercial Office Buildings
Ideal for open workspaces, multi-floor corridors and meeting room clusters—enables zoned constant light control via daylight harvesting, reduces energy waste by adjusting artificial lighting based on natural light, and supports one-touch scene recall (office mode, meeting mode, after-hours mode).
Retail & Hospitality Complexes
Controls display lighting, ambient lighting and common area illumination in shopping malls, hotels and banquet halls. 4-channel independent programming caters to different business zones (retail kiosks, hotel lobbies, banquet halls) with MDRC for synchronized multi-device control.
Industrial & Logistics Facilities
Delivers reliable high-load lighting control for production workshops, warehouse zones and loading docks. Supports automated on/off/dimming based on production schedules and occupancy, with robust 16A per channel capacity for industrial-grade luminaires.
Public Institutions & Municipal Buildings
Applied in schools, hospitals, government buildings and metro stations—manages classroom/ward lighting (constant brightness for eye comfort) and staircase/corridor lighting (staircase timer function for energy saving), complying with public facility safety and efficiency standards.
KNX Smart Building System Integration
Serves as a master control device in ABB i-bus® KNX systems, seamlessly connecting SD/S switch-dim actuators, DG/S DALI gateways and other KNX devices to build a unified, scalable lighting control system for mixed-use towers, business parks and large residential complexes.
