Second, the advantages of HDL-BUS system ● Simple circuit, easy installation, easy maintenance, energy saving, saving large area wire consumption, can reduce the investment cost and use cost of construction developers, shorten the installation period and improve the return on investment.
● It can realize single-point, double-point, multi-point, area, group control, brightness hand/automatic adjustment, infrared monitoring, remote control, centralized monitoring and other lighting control tasks to save energy.
Traditional lighting wiring must achieve special wiring between the switch and the switch if it is to achieve multiple switches to control the same load. The design is complicated and consumes a large amount of wire to extend the construction time. Especially in large buildings, it is very difficult to achieve multi-point control with traditional wiring. In the HDL-BUS system, the switch only needs to be connected in parallel to the HDL-BUS bus, and the multi-point control can be easily realized by setting the control address of the switch with software.
● According to user needs and changes in the external environment, just modify the software settings, instead of modifying the line, you can adjust the lighting layout and expansion functions, suitable for different use requirements of commercial, industrial, and home.
After the traditional wiring or the general two-wire lighting system is installed, if the design or expansion function needs to be changed, the wiring or the control components will be re-wired, which will increase the cost and affect the normal operation of the building lighting system. The HDL-BUS can be easily modified by software to control its function and the load loop it controls.
● When the building is powered off, since the system status and control commands are stored in each input and output component of the HDL-BUS system, when the power is restored, the system will resume normal operation and achieve unattended operation.
● The control circuit is separated from the load circuit. The working voltage of the control circuit is a safe voltage of DC24V to ensure personal safety.
The HDL-BUS system is open and can be combined with other building management systems (BMS), building automation systems (BA), closed-circuit monitoring systems, security and fire protection systems to meet the trend of modern life.
