LK-MA Intelligent Multi-channel Wireless Transmission Module |
Main Features：
●Used to realize 1-to-1 and many-to-many "acquisition-restoration" of analog quantities.
●No programming required, replaces wired transmission, and is plug-and-play.
●Strong anti-interference capability, suitable for signal transmission in harsh environments.
●3000-meter transmission distance (without obstruction), extremely low power consumption (approximately 0.5W)
●Can operate in the public frequency band, no need to apply for a frequency use license.
●Can connect to devices such as PLC, industrial computer, laptop, and single-chip microcomputer.
