• 35.CAN bus communication interface isolator (built-in DC/DC isolated power supply): ISO CAN series

  • SunYuan ISO CAN is an isolated universal CAN bus transceiver module.The module has built-in CAN bus communication interface signal isolation and transceiver devices, which has the advantages of low cost, small size, and convenient use.Its main function is to isolate the logic level of the CAN bus controller into the differential level of the bus. The isolation voltage is as high as 3000VDC during signal transmission. ISO CAN bus communication interface signal isolation module, which integrates DC-DC power isolation circuit, high-speed digital isolation chip, CAN bus transceiver, bus communication protection circuit, etc.In the actual application of the industrial field, in order to prevent the loss or distortion failure caused by the interference during the data transmission and reception process, it is necessary to properly isolate the entire communication circuit.Isolation prevents some modules in the circuit from interfering with each other. For digital circuits, high-speed level conversion will bring a lot of noise, and the grounding network will also introduce noise, so isolation is required.An isolation system must be considered from three aspects: power supply, ground wire network, and signal transmission line. The ISO CAN bus communication interface signal isolation module is easy to use and can realize the function of signal isolation and transmission.The 3KV isolated power supply between the input and output of its internal power isolation circuit, the output has a long-term self-recovery overload short-circuit protection function, when the external communication line is short-circuited, the data acquisition communication workload changes greatly, or the CAN bus interface is suspended The output voltage has a small change and will not increase beyond the rated design voltage.It can effectively isolate the ground wire circulation interference, suppress the interference of the communication interface and enhance the anti-static protection function of the communication interface. The built-in DC-DC can provide a set of regulated isolated power supply for other peripheral interface circuits, especially for the industrial field CAN bus, RS232/ RS485 communication, Ethernet RJ45 communication and other interface power supply provide isolated power supply design.Products are widely used in automotive CAN bus control devices, industrial automation equipment, robots, CNC machine tools, parking lot intelligent control, smart home Ethernet Internet of Things communications, medical instruments, power meters, security data acquisition control and other industries.
