CAN bus isolator

(1) Bus speed: Make sure the selected CAN isolator supports the communication speed of your CAN bus system. Different CAN isolators may support different baud rate ranges, so selection needs to be based on actual needs.
(2) Isolation voltage: Consider the electrical noise and interference that may exist in your application environment. Choose a CAN isolator with sufficient isolation voltage to ensure electrical isolation and safety of the system.
(3) Number of isolation channels: Determine the required number of isolation channels based on your CAN bus system architecture. Some CAN isolators provide single channel isolation, while others provide multi-channel isolation.

(4) Interface type and connection form: Check the interface type (such as DB9, M12, etc.) and connection form (such as direct connection, plug-in, etc.) of the CAN isolator to ensure compatibility with your existing equipment and wiring system.
(5) Power requirements: Understand the power requirements and voltage range of the CAN isolator to ensure that your system can provide a stable power supply.
(6) Working environment: Consider environmental factors such as the operating temperature range, humidity and protection level of the CAN isolator to ensure that it can work reliably in your application environment.

(7) Safety certification: If your application needs to comply with specific safety standards or specifications (such as mining intrinsically safe design specifications), please ensure that the selected CAN isolator has obtained the corresponding certification.
(8) Reliability and stability: Choose a CAN isolator brand and model that has been proven by the market and has a good reputation to ensure the reliability and stability of the system.
(9) Cost: On the premise of meeting the performance and functional requirements, consider the cost-effectiveness of the CAN isolator and choose products with higher cost performance.
