LoRaWAN gateway LM100

communicationindustrialIoT

The LM100/LC144 utilizes the latest Low Power Wireless Access (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 LC144, such as voltage inputs and outputs, current inputs and outputs, PWM output and one RS-485 port for Modbus RTU slave.One LM100 RS485 Modbus RTU can connect up to 250pcs LC144 LoRa end nodes for two-way communications where field site analog signals are sent to LM100 and controlled by LM100. The LoRa wireless distance can reach up to 3-6KM distance depending on the environment. The LM/LC144 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. •Transparent Two-Way Modbus Communication by LoRa •LM100 Sends Modbus Control to LC144 LoRa End node •LC144 Send Modbus Data through LM100 Modbus Slave to Modbus Master DMA – Auto Polling RTU function •20 Sets Constant RTU Registers •LC100 Auto Polling & Mapping in Memory Reduce re-transmission time & performance - 0~10V Input / Output •2 Channels 0~10V High Impedance Input- Luminance Sensing •1 Channel 0~10V Open Drained Output, Dimmer Control 4~20mA Input / Output •2 Channels Current Sensing, 0.3%High Accuracy •1 Channel Current Output, 0.3% High Accuracy Tradition Modbus/RTU Operating Mode •Auto re-present Far-End Modbus Data at Local Bus - PWM Output with Duty Cycle Control •5V PWM Output / 10V Open Drained (O.C.) •Duty Cycle Adjustable - 100Hz~1Khz , 0.2% Accuracy
