The products produced by Yijia Industrial Control Electrical Appliance Co., Ltd. have the following applications in the special vehicle industry:

Power system control

-Communication contactor: used to control the start and stop of special vehicle engines, as well as the operation of high-power equipment such as generators and air conditioning compressors. It can withstand high currents and voltages to ensure stable power supply to the power system.

-Relay: It can control auxiliary equipment such as engine cooling fans and fuel pumps, automatically start or stop these devices according to the operating status of the engine and the working requirements of the vehicle, and improve the efficiency and reliability of the power system.

Electrical system control

-Button switch: installed on the driver’s cab or console of special vehicles, used to control the switch of electrical equipment such as the vehicle’s lighting system, wipers, horns, etc., making it convenient for the driver to operate.

-Signal lights: As status indicator lights for the vehicle’s electrical system, such as power indicator lights, charging indicator lights, fault indicator lights, etc., they transmit the working status information of the vehicle’s electrical system to the driver through different colors and flashing frequencies.

Automation Control and Safety Protection

-Time relay: In the automation control system of special vehicles, it is used to control the timed start and stop of equipment. For example, on a fire truck, the fire pump can be started at a fixed time for spraying water.

-Travel switch: installed in the doors, cargo compartments, and other parts of special vehicles, used to detect the opening and closing status of doors. When the door is not closed in place, the alarm device is triggered through a relay to remind the driver to pay attention to safety and prevent accidents during vehicle operation.

Environmental and auxiliary system control

-Solid state relay: Used to control environmental control equipment such as air conditioning systems and ventilation systems in special vehicles, it can achieve precise temperature and humidity control, providing a good working environment for drivers and equipment.

-Intermediate relay: It can amplify and convert the signals detected by vehicle sensors, transmit them to the vehicle’s control system or display devices, such as converting weak signals detected by temperature sensors, pressure sensors, etc. into recognizable control signals, achieving precise control of the vehicle environment and auxiliary systems.
