Bộ chuyển đổi CAN sang RS232 CAN232

CAN232 is used for data exchange between CAN-bus field bus and RS-232 bus interface converter, and supports Modbus RTU protocol. CAN232 interface converter integrated a RS-232 channel and a CAN bus channel can be easily embedded using RS-232 interface for communication nodes, do not need to change the original hardware architecture enables the device to obtain the CAN bus communication interface, to achieve between the equipments of RS-232 and can bus network connection and data communication. RS-232 channel CAN232 devices to support a variety of baud rate, the range is 300bps~115200bps. CAN-bus channel support CiA recommended a variety of standard baud rate and user-defined baud rate, the range of 2.5Kbps~1Mbps. CAN232 interface converter provides three types of data conversion: transparent conversion, encryption conversion and Modbus protocol conversion.
Its exterior design supports DIN-Rail mounting and Wall mounting, which is convenient for engineering application. The board comes with a photoelectric isolation module, complete electrical isolation control circuit and CAN-bus communication circuit, so that the CAN232 converter has a strong anti-interference ability, greatly improving the system in the harsh environment of the use of reliability.
