Wireless Modbus RTU for Stacker/Reclaimer Remote Control
This application is widely used for PLC wireless collect 4-20mA signal and PLC remote control stacker and reclaimer.
Introduction
You could refer the diagram, our wireless RTUs are used to help build wireless communication between stacker and reclaimer machine with its control room. This will reduce much cost and minitor, maintain time.
Here we use LS-RDIO0202+LS-RAI/O expanders, users can get the
4-20mA analog signal and ON-OFF condition of machine in time.
