Among many competitors, Coolmay is one of the most competitive ones. We center on the development and production of modbus hmi. The plc module series is one of the main products of Coolmay. The color of the product is determined by the chemical composition and the tightness of the combination of these compositions. Installing Coolmay's PLC touch screen can save the cost on wiring and construction. People who used it for many years said it does not easily get pilling or fussy balls and it can withstand heavy wear and tear. The PLC controller adopts military-grade chip which makes it of faster operating speed and stronger anti jamming capability.
