AHCPU500-EN | DELTA | Modules CPU

Description

Designed for mid-to-high-range industrial automation tasks, the Delta AHCPU500-EN serves as a reliable programmable logic controller CPU module within the Delta AH Series platform. This controller manages sequence execution, timing, and communication across complex assembly lines and automated systems. It offers high-speed execution capabilities, processing basic ladder diagram instructions in as little as 0.1 microseconds.

The AHCPU500-EN is equipped with integrated communication interfaces including a 100Mbps Ethernet port, a multi-mode RS-232/422/485 serial port, and a mini-USB programming port. This module operates without a backup battery, instead utilizing non-volatile memory and an internal real-time clock that remains active for up to 30 days post-power-down. System integration is simplified through support for multiple IEC 61131-3 compliant programming languages, allowing engineers to structure logic using Ladder Diagram, Sequential Function Chart, Function Block Diagram, Instruction List, or Structured Text.

Features

• Provides a high program capacity of 32K steps (128KB) and extensive data registers (16K D, 16K L, and 512K B words).
• Supports up to 768 local I/O points for robust machine control.
• Built-in 100Mbps Ethernet port supporting MODBUS TCP, NTP network time correction, Web, E-mail, and IP filtering.
• Integrated multi-mode serial port supporting RS-232 (up to 115.2 kbps) and RS-422/485 (up to 921.6 kbps) configurations.
• Equipped with an SD card slot supporting memory expansion up to 2GB.
• Features 256 interrupts including Timed, I/O, External, Low Voltage, and Communication interrupts.
• No backup battery required, lowering long-term system maintenance overhead.

Applications

• Municipal water treatment facilities and pumping stations.
• Automated packaging, sorting, and material handling systems.
• HVAC control and building automation systems.
• Textile machinery and multi-axis assembly systems.

Installation Guidelines

• Ensure the PLC backplane is securely grounded to a low-impedance ground point to minimize electromagnetic interference (EMI).
• Maintain a minimum of 50 mm clearance above and below the CPU module for passive convection cooling.
• Do not insert or remove the SD card or connection cables while the CPU module is powered on.
• Route communication cables separately from high-voltage motor drives and AC power lines to prevent signal degradation.
