4-layer impedance control fine circuit immersion gold PCB circuit board

All the node control modules of the smart home system are connected with the system information control center through the RS485 home control bus and follow the unified home control network communication protocol to realize system data communication. 256 modules can be connected on one bus to realize various functions of home automation control. The module types include:

Wireless transceiver base station module

It is mainly used in conjunction with the wireless remote control module and is a necessary accessory of the system. As a wireless transceiver base station, it transmits the information from the remote control to the system information control center through the home control network, and then transmits the instructions and short message information of the system information control center. It is transmitted to the wireless remote control through the wireless radio frequency signal, which is the place where the wireless information is converted into the wired home control network information;

Relay switch control module

Low power loop control, using high performance solid state relays for control. After receiving the instruction of the smart home controller, the low-power electrical appliances in the home, mainly lights (including various audio systems, TV sets, and electric curtains) are switched on and off, and the control power is 100 watts per circuit;

High-power electrical appliance control module: It is also controlled by solid-state relays, but its power is large and only has a single channel. After receiving the instruction of the smart home controller, it can switch the high-power electrical appliances (such as air conditioners and water heaters) in the home. Control, the control power is a maximum of 2,500 watts for a single circuit;

SCR dimming control module

SCR is used for low power loop control. After receiving the instruction of the smart home controller, its function is mainly to control the dimming of the lights in the home, the control power is 100 watts per circuit, and the dimming range is divided into 5 grades: 0, 25%, 50%, 75 %, 100%;

Information switch module

The information switch has completely changed the original switch concept. The switch information point is used to complete the function of the original switch, so that the original switch function is fixed and single. By setting the relevant control parameters, any control point can be controlled to achieve Group control function.
