Delta AHCPU531-EN PLC Controller

The Delta AHCPU531-EN PLC is a modular, high-performance PLC designed for large-scale automation systems. It offers fast execution speeds, supports up to 1 million program steps, and handles thousands of I/O points, making it ideal for complex applications. With hot-swappable modules, redundant power, advanced motion control, and support for multiple communication protocols, it ensures flexibility and reliability. Programming is done via Delta’s ISPSoft software, compliant with IEC 61131-3 standards, making the AH500 suitable for industries like packaging, HVAC, and machine tools. The AHCPU531-EN PLC also supports precise multi-axis control via EtherCAT, with functions like interpolation and synchronous control. The AH500’s scalable design makes it a future-ready choice for expanding industrial automation needs.
