The CJMCU-2551 is a fault tolerant high-speed CAN device that acts as a CAN protocol controller and a bus interface. The MCP2551 provides differential transceiver capability for the CAN protocol controller, which fully complies with the -11898 standard, including 24V voltage requirements.Typically, each node on the CAN system must have a device that converts the digital signal generated by the CAN controller into a signal suitable for bus transmission. It also adds buffers between the CAN controller and the high voltage spikes on the CAN bus, which may be generated by external devices.Support 1MB / S operating rate.Meet the -11898 standard layer requirements.Suitable for 12V and 24V . Slope External Control, Reduced RFI.Automatically detects a ground fault at the TXD input.Power-on reset and voltage event undervoltage protection.No power-up node or undervoltage does not affect the CAN bus.Low current standby operation.Up to 112 nodes can be connected.Material: Metalsize: 18 x 15mmColour: Purple: 1 pcsPackage Contents: 1 x CAN Communication Protocol Controller Bus Interface ModuleNote: Light and different displays may cause the color of the item in the picture a little different from the real thing.
