The AP100-LM/AP144-LC utilizes the latest Low Power Wide Area (LPWA) technology to build Modbus/RTU communication for long-distance, wide- coverage, and low power consumption wireless IoT applications. Multiple analog inputs and outputs are supported in AP144-LC, such as voltage inputs and outputs, current inputs and outputs, PWM output and one RS-485 port for Modbus RTU slave. One AP100-LM RS485 Modbus RTU can connect up to 250pcs AP144-LC LoRa end nodes for two-way communications where field site analog signals are sent from AP144-LC and controlled by AP100-LM. The LoRa wireless distance can reach up to 3-6KM distance depending on the environment. The AP144-LC/AP100-LM offers great flexibility in wireless IoT applications, such as LED light control, environment sensors and meters reading for Smart City Applications such as Lighting, Smart Farming, Smart Environment Monitor, etc.
