The LM200/LC144 series utilizes the wireless LoRa technology to extend Modbus/RTU and Analog Input Output transmission with long-distance, wide-coverage, and low power consumption LPWAN network. LM200 is the LoRa Master to receive and send multiple LC144 LoRa Controllers Analog Inputs, Outputs or Modbus RS485 data. Rule Chain can be configured in LM200 to pair or mirror two LC144 controllers, or to group multiple LC144 for logic control. One LM200 can connect up to 250pcs LC100 LoRa nodes and LoRa wireless distance can reach up to 3-6KM. LC144 supports multiple analog inputs and outputs, such as voltage inputs and outputs, current inputs and outputs, PWM output and one RS-485 port for Modbus RTU slave for different IoT applications. The LM200 and LC144 offer great flexibility in wireless IoT applications, such as LED light control or analog signals reproduced at remote site to replace traditional wiring.
