Product introduction     

  This product is a multi-functional power distribution box, featuring 12 output controls, including 9 relays, 3 MOSFETs, multiple communication interfaces (dual CAN, RS485, RS232), and rich sensor detection functions (water temperature, temperature, high and low voltage monitoring). It is suitable for scenarios such as energy management and in-vehicle equipment. Provide stable and reliable remote control and real-time monitoring solutions.

Multi-channel output control

9-channel relays: Support normally open/normally closed, including 5 channels of 10A and 4 channels of 25A, suitable for switch control of lighting, motors, equipment power supplies, etc.

3-channel MOSFET: Supports PWM regulation, can drive DC loads (such as fans, LED light strips), and has overcurrent protection function.

Industrial-grade communication interface

Dual-channel CAN bus: Compatible with CAN 2.0A/B protocol, suitable for automotive electronics and industrial fieldbus communication.

RS485: Supports Modbus RTU protocol, can be networked for multi-device communication, and has strong anti-interference ability.

RS232: It is used for local debugging or direct connection to the upper computer, and the configuration is simple.

Environmental monitoring and safety protection

Two-channel water level and water temperature detection: Real-time monitoring of water tank liquid level and temperature.

Two-channel temperature detection: Monitor the ambient temperature inside and outside the vehicle, ranging from -40℃ to 125℃. 12-channel high and low voltage detection: Abnormal trigger alarm or automatic power-off protection.
