A Complete Overview of Delta PLC Product Lines: From Entry-Level to High-End

As a globally leading industrial automation brand, Delta offers a comprehensive PLC product matrix ranging from entry-level compact controllers to high-end modular controllers, meeting the diverse control requirements of various industrial scenarios. Below is an introduction to Delta's main PLC series:

1. AX-5 Series: High-End Modular Controllers
The Delta AX-5 Series is a high-end modular controller capable of synchronously controlling mechanical movements involving servo drives, VFDs, and remote I/O modules. The series features an ultra-slim 12mm I/O design to reduce cabinet installation space. Its independent I/O power supply simplifies wiring, ensuring highly stable system operation and flexible expansion of I/O modules. The AX-5 Series also offers user-friendly IoT capabilities, supporting FTP and Type-C USB for convenient remote maintenance and on-site instant programming and debugging.

2. AH Series: High-End Modular Controllers
Delta's AH Series modular controllers provide complete automation system solutions for high-end applications. Featuring a fully modular design, the AH Series is characterized by a rich library of Function Blocks (FBs), high cost-effectiveness, and versatile expansion capabilities, offering excellent system scalability. The series includes a dedicated motion control CPU that connects to servo drives via an EtherCAT motion control network, enabling high-speed, high-precision machine control. The AH500 Series supports a complete redundant architecture with dual CPUs, dual main backplanes, dual power supplies, and dual communication channels.

3. AS Series: High-Performance General-Purpose Controllers
The Delta AS Series PLC is a high-performance, general-purpose controller specifically designed for automated equipment. Powered by Delta's proprietary 32-bit SoC CPU, it delivers a significant performance boost of up to 40k steps/ms, with expandability of up to 32 modules or a maximum of 1,024 I/O points. Its powerful positioning control function can simultaneously support up to 8 axes via a CANopen motion network or 6 axes with 200 kHz pulse control. The AS Series motion control CPUs feature multiple built-in communication ports and dedicated motion control network interfaces (EtherCAT/CANopen), supporting synchronous control of up to 16/24 physical axes. The AS Series is ideal for automation control in industries such as electronics manufacturing, packaging, printing, textiles, and pharmaceuticals.

4. DVP Series: Classic Compact PLCs
Delta's DVP Series Programmable Logic Controllers are widely used in various industrial automation machinery, renowned for their high-speed robustness and high reliability. Key features include fast logic execution, a rich instruction set, versatile expansion capabilities, high cost-effectiveness, and support for multiple communication protocols. The DVP Series comprises several sub-series, including the DVP-ES2/EX2 standard main units, DVP-EH3 high-performance PLCs, DVP-S Series slim main units, and DVP-SV2 high-performance slim main units.
