Product Description
The CJMCU-2551 MCP2551 CAN Protocol Controller High-speed Interface Module is a device that can communicate with the CAN protocol at high speed and with fault tolerance. It connects the CAN protocol to the physical bus and provides differential transmission and reception. The device meets the ISO-11898 standard, including the 24V requirements. It can achieve a data transfer rate of up to 1Mb/s.
The module also protects the CAN controller from high-voltage spikes that may occur on the CAN bus due to external sources such as EMI, ESD, electrical transients, etc.
