The AC500 and AC31 series are modular programmable controllers offering scalable automation solutions. They support a wide range of I/O modules, human‑machine interfaces, and up to five integrated communication ports, allowing flexible integration with various fieldbus systems.
The document details hardware specifications such as supply voltage, memory sizes, and I/O capacities, describes the supported IEC 61131‑3 programming languages, and lists the available communication modules and ordering information for CPUs, I/O boards, and accessories. This manual is written in Chinese.
| Supply voltage | 24 V DC |
|---|---|
| Data memory | 24 KB (including 4 KB retain) |
| Maximum local I/O points | DI/DO 224 points (centralized) |
| Maximum analog inputs | 160 |
| COM1 interface | RS232 / RS485 (configurable) |
| Supported programming languages | FBD, IL, LD, ST, SFC, CFC |
The controllers support six IEC 61131‑3 languages: Function Block Diagram (FBD), Instruction List (IL), Ladder Diagram (LD), Structured Text (ST), Sequential Function Chart (SFC) and Continuous Function Chart (CFC).
Up to 224 digital input/output points can be configured in a centralized expansion configuration.
All CPU and I/O modules operate from a 24 V DC power supply.
