Coolmay HMI/PLC all-in-one machine has innovatively realized the high integration of HMI and PLC switch, analog and temperature in hardware. It can be used in various occasions requiring PLC control without external PLC and other expansion modules. The highly integrated industrial automation control solution uses pluggable terminals, which greatly facilitates the disassembly, installation and maintenance of terminal customers. It can be replaced directly when it fails, achieving "zero travel expenses" and free on-site maintenance.
