CAN485

CAN485 is used for data exchange between CAN-bus field bus and RS-485 bus interface converter, and supports Modbus RTU protocol.

CAN485 interface converter integrated a RS-485 channel and a CAN bus channel can be easily embedded using RS-485 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-485 and can bus network connection and data communication. RS-485 channel CAN485 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. CAN485 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 CAN485 converter has a strong anti-interference ability, greatly improving the system in the harsh environment of the use of reliability.
