Hello,
Program description:
This solution uses the 24V DC bus power supply of the system that controls the scene, and the equipment converts the common CAN (Controller Area Network) communication method of the scene into an Ethernet signal, so as to realize the communication and interconnection between the scene and the Internet.
Power supply:
The 24V voltage is converted to the board-level 5V voltage for the transceiver for network communication, and the LDO steps down the 5V voltage to 3.3V to supply power to the MCU. At the same time, 05V isolation supplies power to CAN controllers, electromagnetic isolation devices and CAN transceivers, and they send the signals to the CAN bus to realize the isolation conversion of communication signals.
Program features:
Long transmission distance, the maximum transmission distance of optical fiber can reach 60kilometers. Unique CAN baud rate automatic adaptation technology, no need to set, CAN baud rate 0～1Mbps (configuration-free mode, factory default); optical fiber transmission CAN network data; transparent Transmission, support CAN2.0A, CAN2.0B, comply with ISO/DIS 11898 specification; CAN interface 3000V DC-DC isolation, 2500V signal isolation; Optical fiber isolation, lightning protection, surge, electromagnetic interference.
