PLC RF Link Module, Modbus RTU protocol, PLC wireless communication
Introduction:
LS-R324 is a 1W radio modem, transmit 3km LOS. It supports UHF band, 24V power supply. Usually works as 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.
