Specification

The DELTA PLC CONTROLLER AH SERIES REDUNDANT CPU is a high-performance, modular programmable logic controller designed for advanced automation systems requiring fault tolerance and uninterrupted operation. This CPU module, part of the Delta AH series, integrates a redundant architecture that automatically switches control in the event of a primary unit failure, making it ideal for critical processes in manufacturing, energy, and infrastructure. With IEC 61131-3 compliance, it supports multiple programming languages including Ladder Diagram (LD), Continuous Function Chart (CFC), Structured Text (ST), and Sequential Function Chart (SFC). The unit features a cyclic execution model with direct I/O refresh capabilities, ensuring deterministic response times. Its robust hardware includes DIN rail or screw mounting, backplane-based module installation, and a wide range of built-in communication interfaces for seamless integration into existing networks.
