Tips: 8-channel RS485 converter in the installation and use of precautions

When installing, please make sure the module converter is connected stably and the wiring ports correspond correctly. In order to avoid signal interference, it is recommended that the analog signal lines and power lines be wired separately. The device supports standard DIN rail mounting, which is convenient to integrate with the control cabinet. When supplying power, please choose a stable power supply to avoid affecting the performance due to voltage fluctuation. In addition, during use, ensure that the RS485 converter operates within the specified temperature and humidity ranges to extend its service life.
