WoMaster LoRa Modbus Analog I/O Controller LM100/LC100 Series Complete LoRa Controller for Analog In/Out, PWM Output, and RS485 The LM100/LC100 series utilizes the latest Low Power Wide Area (LPWA) technology to build Modbus/RTU communication for long-distance, wide-coverage, and low power consumption wireless loT applications. Multiple analog inputs and outputs are supported in LC100 series, 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 LC100 LoRa end nodes for two-way communications where field site analog signals are sent from LC100 and controlled by LM100. The LoRa wireless distance can reach up to 3-6KM distance depending on the environment. The LM100/LC100 series offers great flexibility in wireless loT applications, such as LED light control, environment sensors and meters reading for Smart City Applications such as Lighting, Smart Farming, Smart Environment Monitor, etc. LoRa Modbus Modbus/RTU Extension by LoRa • Transparent Two-Way Modbus Communication by LoRa • LM100 Sends Modbus Control to LC100 series LoRa End node • LC100 series Sends Modbus Data through LM100 Modbus Agent to Modbus Master Device Tradition Modbus/RTU Operating Mode • Utilize Modbus/RTU protocol for LoRa Agent / LoRa Node configure and communication • Auto forward Modbus Data to Far-End node • Auto re-present Far-End Modbus Data at Local Bus Reliable LoRaMAC Radio Communication • ECHO & Re-Send mechanism - LoRa Agent / LoRa Node • Configurable Retransmit Mechanism- LoRa Agent Secured Radio Communication • AES 128 Data Encryption • Configurable Encryption Key - Modbus Register , WoMaster End-Node Utility Windows© Configure Tools • User-Friendly, Model Auto Detection • Analog IO Parameter Read and Write • Micro-USB Interface 0~10V Input / Output • 2 Channels 0~10V High Impedance Input- Luminance Sensing • 1 Channel 0~10V Open Drain Output, Dimmer Control 4~20mA Input / Output • 2 Channels Current Sensing, 0.3%High Accuracy • 1 Channel Current Output, 0.3% High Accuracy PWM Output with Duty Cycle Control • 5V PWM Output / 10V Open Collect (O.C.) • Duty Cycle Adjustable - 100Hz~1 Khz , 0.2% Accuracy RS485-Modbus/RTU • Modbus/ RTU Slave Mode - LM100 • Modbus/RTU Host Mode - LC100 • 2-Wires RS-485 Industrial Application • 10~30V DC wide power range input • Low Power Consumption • Wide Coverage up to 6KM • Max.250 LC100 Nodes to one LM100 • -40 ~ 75°C / 90%H Operating Temperature / Humidity • Compliance IEC 61000-6-2/-6-4 Heavy Industrial EMC
