Analog converter LR144 series

powerRS-485Modbus

The LR144 series utilizes the latest Low Power Wide Area (LPWA) technology to build long-distance, wide-coverage, and low-power wireless IoT applications. Multiple analog inputs and outputs are supported in the LR144 series, such as 0-10V, 4-20mA current, 5V PWM, 0-10V PWM for traditional electromechanical control and sensing, and the RS-485 port supports Modbus Host mode for the filed site automation controller- PLC, DCS or any device with Modbus communication interface. Its regular Modbus register data pulling function ensure the control center gets the latest data. The LR144 series offers great flexibilities in wireless IoT applications, such as traditional analog sensors acquisition and Modbus/RTU devices remote control, integrated with LoRa WAN gateway that can achieved edge computing/control and enhanced your Industrial IoT process such WR322GR LoRaWAN series. •Lowest latency for server-to-end-device communication •Supports Spreading Factor 5,6,7,8,9,10,11,12 Reliable Radio Communication • LoRa WAN TX Confirmed Mode support •Adjustable LoRa Data Upload Interval time •Remote Control with End-Node Acknowledge •Maximum 20 RTU Entries, Scheduling polling •Non-Limited RTU Entry for Downlink Control •Code 01: Read Coil-Read Output Control bit •Code 02: Read Discreet-Read Input bit, Read Input bit •Code 03: Read Holding Register – Read Output word •Code 04: Read Input Registers – Read Input Word •Code 05: Write Single Coils – Write one bit output •Code 06: Write Single Coils – Write one word output •Code 15: Write Multiple Coils – Write a number of output bits •Code 16: Write Multiple Registers - Write a number of output words
