AH Series - Hot Swappable Midrange PLC

AH Series PLC provides automation solutions for high-level applications. The combination of modularized hardware structure, advanced functions, and the highly integrated software provides a system solution for process control applications. In addition to various function blocks (FB), excellent price/performance, and an abundant selection of extension modules, AH Series PLC also provides multi-axis motion control via motion network, such as EtherCAT, to perform high-speed, high-precision machine control. The exceptional system expandability also greatly reduces the system cost for a broad range of applications.
