Wireless Modbus DTU PLC Remote Control Sensors And Pumps Wireless Communication System
Use LS-R324 as master, it connects with your PLC/HMI via RS485/RS232 port.
LS-R324 is a 1W radio modem, transmit 3km LOS. It supports UHF band, 24V power supply. Usually works as wireless DTU to connect with PLC and other industrial control devices. LS-R324 Supports RS485 Modbus RTU protocol. Has the advantage of register data restore function.
