coolmay EX3U Series: High-Efficiency Automation HMI/PLC All-in-One

In 2005, coolmay pioneered the HMI/PLC all-in-one, reshaping automation with high integration, compact size and powerful performance. Celebrating its 20th anniversary in 2025, coolmay leverages over 20 years of 100% full-chain independent R&D to launch the EX3U Series, delivering precise cost-saving and efficiency-boosting automation solutions for global manufacturers.

Equipped with a military-grade 32-bit CPU + ASIC dual-processor, the EX3U Series offers a 0.24-microsecond maximum basic instruction speed and 30k-step program capacity. It supports online monitoring and downloading for easy operation and fast response, laying a solid hardware foundation for efficient automation.

It boasts 6 channels of 200KHz high-speed counting, 6 channels of 200KHz high-speed pulses and external interrupts, balancing precision and efficiency. Supporting digital/analog plug-in expansion, it can extend to 30 inputs and 28 outputs with an optional 6-in-8-out module, adapting to diverse automation scenarios.

Optional CAN, Ethernet and coolmay WIFI/4G IoT modules enable remote management via the coolmay cloud platform (plug-and-play for low IoT transformation costs). Compatible with Modbus TCP, MC and EtherNET/IP protocols, it supports flexible network building and U-disk upload/download for improved O&M efficiency.

Focused on full-process cost optimization, the EX3U Series cuts operating costs and boosts overall benefits via its "Three-Zero" features.

• Zero Assembly Cost: High integration eliminates extra connectors, enclosures and terminals, simplifying assembly and saving labor/material costs.

• Zero Labor Cost: Covering R&D, assembly and after-sales, it requires no extra enterprise manpower, enabling focus on core businesses.

• Zero After-Sales Cost: Plug-and-play terminals allow non-professional assembly/disassembly, eliminating on-site services and travel costs.

Integrating logic control, touch screen, current/voltage collection, thermistor/thermocouple detection and weighing, it features compact design and flexible installation for seamless adaptation to diverse scenarios, completing complex tasks without multiple devices.

60% smaller than traditional equipment, it saves installation space, fitting narrow workstations and complex production lines to optimize on-site layout.

With independently developed firmware (full IP rights), it achieves end-to-end control over hardware, firmware and software, ensuring compatibility and stability. Trusted by over 40,000 global manufacturers.

Comprehensive customization (hardware, function, appearance, software) is available. Leveraging 20+ years of software expertise, it enables "zero development time/cost" with fast hardware-based customization for rapid launch.

From industry pioneer to 20 years of innovation, coolmay upholds "Making Automation Simpler". The EX3U Series empowers global manufacturers with strong performance, "Three-Zero" advantages and customization, enabling more efficient, economical and convenient automation.
