ISO CAN Bus Isolator with Integrated DC-DC Power

SunYuan ISO CAN is an isolated universal CAN bus transceiver module. The module has built-in CANbuscommunication interface signal isolation and transceiver devices, which has the advantages of lowcost, small size, andconvenient use. Its main function is to isolate the logic level of the CAN bus controller into the differential level of thebus, and the isolation voltage is as high as 3000VDC during signal transmission.

ISO CAN bus communication interface signal isolation module, which integrates DC-DC power isolationcircuit,high speed digital isolation chip, CAN bus transceiver, bus communication protection circuit, etc. In the actual applicationof the industrial field, in order to prevent the loss or distortion caused by interference during the data transmissionandreception process, it is necessary to properly isolate the entire communication circuit. Isolation prevents some modulesinthe circuit from interfering with each other. For digital circuits, high speed level conversion will bring a lot of noise, andthe ground wire network will also lead into noise, so isolation is required. An isolation system must be consideredfromthree 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 functionofsignal isolation and transmission. The 3KV isolation power supply between the input and output of its internal powerisolation circuit, the output terminal has a long-term self-recovery overload short-circuit protection function, whentheexternal communication line is short-circuited, the data acquisition communication workload changes greatly, or theCANbus interface is suspended The output voltage has a small change and will not increase beyond the rated designvoltage. Itcan effectively isolate the ground wire circulation interference, suppress the interference of the communicationinterfaceand enhance the antistatic protection function of the communication interface. The built-in DC-DC can provideaset ofregulated isolated power supply for other peripheral interface circuits, especially for the industrial field CANbus, RS232/RS485 communication, Ethernet RJ45 communication and other interface power supply provide isolated power supplydesign. Products are widely used in car CAN bus control devices, industrial automation equipment, robots, CNCmachinetools, parking lot intelligent control, smart home Ethernet Internet of Things communications, medical instruments, powermeters, security data acquisition control and other industries.
