The Advanced Digital Load Controller expands the capabilities of a digital room system by integrating scene control, time-based scheduling, and astronomical clock functionality. These functions allow complex lighting behaviors to be configured and managed directly through a mobile application available for both iOS and Android devices. In addition to these advanced options, the unit provides standard switching and 0–10V dimming control for LED drivers and ballasts. A robust 16-amp relay, managed by an intelligent microprocessor, ensures optimized switching performance and extended relay life even when handling high-inrush LED loads.
Installation of the controller is designed to be straightforward and efficient. The housing includes an elongated chase nipple with snap-fit design for quick mounting, while a built-in test and programming button streamlines commissioning and troubleshooting. As with all products in the family, this controller is proudly made in the USA and built to reduce contractor labor time without compromising reliability or performance.
The controller communicates through a topology-free, three-wire digital data line, eliminating the complexities and limitations associated with CAT-5 based systems. Standard 18/3 cable and wire nuts are used for interconnection, allowing flexible wiring layouts and simplified integration. Communication across the data line is managed using a proprietary, digitally encrypted protocol that ensures secure operation and reliable device interaction. Each load controller is individually addressable and can be digitally zoned with compatible wall stations and sensors through three configuration options: a default single-zone mode, a push-button pairing method for multi-zone systems, or the mobile configuration app for complete customization.
Once connected, the mobile app automatically discovers all digital devices on the network, maintaining any existing pairings and enabling the addition of new control zones. These zones can be configured with specific operating modes, dimming levels, and photocell parameters to meet precise lighting requirements. The app also enables the creation of custom lighting scenes that adjust zone behavior based on occupancy, vacancy, high/low trim, or desired lighting levels. Scenes can be activated manually via a scene selector wall station or automatically through time-of-day and astronomical clock schedules.
The Advanced Digital Load Controller greatly simplifies code compliance and application setup. A digital room can be assembled using only a 3-wire connection linking SWD-900 Series load controllers, SWD-200/400 Series sensors, and SWD-800 Series wall stations. Devices are easily zoned using the same push-to-pair procedure found in the wireless platform or configured through the mobile app. By incorporating a single SWD-940 Advanced Load Controller, users gain access to full time scheduling, astronomical control, and mobile configuration without needing to access ceilings or fixtures directly.
The system supports a wide variety of applications such as classrooms, conference rooms, open areas, small offices, copy rooms, private restrooms, hallways, and break rooms. It enables configuration for occupancy, vacancy, partial-on, partial-off, daylight harvesting, and multi-way dimming or switching scenarios. The result is a powerful, flexible lighting control solution that adapts to diverse commercial and educational environments while maintaining ease of setup and operation.
Physically, the controller measures 3.00 inches high, 2.25 inches wide, and 1.88 inches deep (7.62 cm x 5.72 cm x 4.78 cm) and weighs 6 ounces. It is housed in a black enclosure designed for ½-inch knockout mounting and includes a bi-color white and blue LED status indicator alongside a convenient test/programming button. The digital data line connection consists of three wires—power, common, and digital data—using 18/3 cable. The communication range extends up to 1000 feet point-to-point and 4000 feet total bus length, maintaining data integrity over long runs.
The unit’s wireless capability uses Bluetooth Low Energy (BLE) on the 2.4 GHz frequency band, with a typical range of up to 50 feet without obstructions. This allows seamless connection to the mobile app for system setup, monitoring, and configuration.
Electrically, the controller supports an operating voltage of 120–277 VAC, single phase, 60 Hz. It includes a Class 2 power output of 15 VDC at 70mA for digital accessories. The relay is rated for 16A at 120–277 VAC across general-purpose, tungsten, magnetic ballast, electronic ballast, and LED driver loads. It also supports DC loads up to 16A at 28 VDC and motor loads up to 1 HP at 250 VAC. The dimming control output supports up to 50mA (0–10 VDC) for ballasts or drivers compliant with IEC 60929 Annex E.2. The relays utilize zero-cross switching technology for enhanced longevity and reduced electrical stress.
To protect against environmental and electrical hazards, the unit is tested for electrostatic discharge (ESD) immunity and includes non-volatile memory for data retention during power loss. A rechargeable backup battery maintains clock and schedule integrity for up to one year when unpowered.
The controller supports multiple operating modes, including Occupancy, Vacancy, Partial On, Partial Off, Daylight Harvesting, On/Off/Inhibit Photocell, and Ignore Occupancy or Switches. Configurable time delay options range from 1 minute to 8 hours, with additional custom settings available through the mobile app.
Environmentally, the device operates within a temperature range of 32°F to 122°F (0°C to 50°C), with an optional -HE variant extending tolerance to -40°F/C, and functions in 0–95% non-condensing relative humidity for indoor applications only.
Overall, the Advanced Digital Load Controller integrates precision control, flexible installation, and intelligent configuration capabilities into a compact, durable form factor—making it a central component of a modern digital lighting control system that balances simplicity, scalability, and performance.
