Coolmay EX3S Series: Cost-Effective PLC All-in-One for SME Automation
Amid industrial automation, SMEs face challenges of low integration, high maintenance costs, and steep learning curves. Shenzhen Coolmay’s EX3S Series Economical PLC All-in-One addresses these pain points with "high integration, efficiency, and robust functions," simplifying traditional split-system complexity into a cost-effective integrated solution.
Integrated Innovation: One Device, Full-Scenario Control
The EX3S Series’ game-changing advantage is its engineering-free integrated design, combining 8 core functions (logic control, HMI, analog I/O, temperature/weighing modules) into one unit. It reduces volume by 60% and cuts hardware costs by 50% compared to traditional decentralized equipment. All core components (HMI, PLC, high-speed pulses, RS485/WIFI) are included, eliminating extra module purchases and solving wiring/compatibility issues.
Installation and maintenance are user-friendly: a simple screw-fix design allows non-professionals to install/disassemble without complex accessories. External pluggable terminals enable self-repair, reducing after-sales travel costs and downtime.
Functionally, the high-end EX3S-8070H supports up to 24 digital inputs/20 outputs and 4 analog inputs/2 outputs, connecting seamlessly to sensors, inverters, and instruments. Three built-in communication ports (2×RS232 + 1×RS485) support Mitsubishi and Modbus protocols, enabling intelligent IoT networks for single-machine or production line control.
Performance Leap: Speed, Precision, and Usability
Equipped with a military-grade 32-bit CPU + ASIC dual-processor, the EX3S delivers microsecond-level response (0.24us basic instruction speed, 30k-step program capacity). It supports 6-channel 100KHz single-phase or 2-channel 60KHz AB-phase high-speed counting, plus 4-channel 100KHz pulse output for precision motion control.
Usability is prioritized: compatibility with Mitsubishi instruction sets and GX Works2 software allows seamless onboarding for experienced engineers. The 16.77M true-color resistive touch screen (4.3"/7.0" sizes, vertical display) and 1GHz CPU/128MB RAM ensure smooth operation.
NOR Flash storage (100,000-1,000,000 erasures) enhances durability. U-disk one-key program upload/download and optional 4G/WIFI enable remote programming, monitoring, and upgrades, boosting maintenance efficiency.
Full Product Matrix & Competitive Edge
The EX3S Series offers diverse models: 12I/12O entry-level (EX3S-8043H) to 24I/20O high-end (EX3S-8070H), with relay (MR), transistor (MT), and mixed (MRT) outputs. Analog I/O supports 0-10V voltage/0-20mA current, with 4/6 optional channels for flexibility.
Versus the Xinje ZG Series, the EX3S has clear advantages: 44 maximum I/O points (vs. 30), built-in analog I/O (no extra BD boards), superior high-speed counting/pulse output, and a wider operating temperature range (-20℃~50℃) for harsh environments.
Conclusion: SME Automation Benchmark
The Coolmay EX3S Series solves SMEs’ core automation pain points with integrated design, strong performance, and cost efficiency. It supports equipment transformation, production line linkage, and IoT setup, while remote maintenance reduces operational costs. For SMEs seeking affordable, low-threshold automation, the EX3S is a "cost-reducing, efficiency-enhancing" tool and a benchmark in industrial automation.
