AH64AN02P-5C DELTA AH500 Series 64-Point Digital Output Module

Product Overview

The AH64AN02P-5C (AH64AN02P5C) is a high-density digital output module designed for Delta’s AH500 modular PLC system. This module provides 64 integrated output points, utilizing PNP (Source) logic to drive industrial field devices such as solenoid valves, pilot lights, and interposing relays. Engineered for large-scale automation projects where cabinet space is at a premium, the AH64AN02P-5C utilizes latched connectors for efficient wiring and supports hot-swapping, allowing the module to be replaced without shutting down the entire system. With built-in diagnostic features like the "keep-last-value" function, this module ensures process stability even during CPU transitions or maintenance events.

Technical Configuration

The AH64AN02P-5C hardware is optimized for high-reliability signal distribution. Each of the 64 points is rated for 12 to 24 VDC at 0.1 A, making it ideal for driving high-impedance loads and electronic inputs. The unit features 32 individual LED status indicators that can be toggled to monitor all 64 points in banks, providing instant local diagnostics. A critical safety feature is the Keep-Last-Value function, which allows the user to configure whether outputs should turn off or maintain their current state if the CPU enters a STOP mode or loses communication. For wiring efficiency, the module is designed to interface with external terminal blocks via specialized ribbon cables (DVPACAB series), significantly reducing manual point-to-point wiring time.

Technical FAQs

What is the benefit of the "Keep-Last-Value" function?

In specific industrial processes, a sudden loss of control signal can be hazardous (e.g., stopping a cooling fan or closing a critical valve). The AH64AN02P-5C allows the hardware to "latch" the last known state from the CPU, ensuring the field device stays in its safe orientation until manual intervention or a system reboot occurs.

Does the module support hot-swapping?

Yes. As part of the AH500 architecture, the AH64AN02P-5C can be removed and replaced while the backplane is powered and the rest of the PLC is running. This is a vital feature for high-availability manufacturing environments where stopping the entire line for a single module replacement is not feasible.

How do I manage the wiring for 64 points with a latched connector?

Delta provides pre-assembled cable and terminal block sets (sold separately). For this module, you can use two DVPACAB7B10 cables connected to four DVPAETB-OR16B relay boards, or two DVPACAB7A10 cables connected to two DVPAETB-OT32A terminal blocks. This modular approach ensures a "plug-and-play" installation with minimal chance of wiring errors.

Engineering & Installation Guide

• Load Management: The 0.1 A rating per point is designed for logic signals and small solenoids. If you need to drive high-current loads (e.g., large contactors or motors), always use an external interposing relay board. Exceeding the 0.1 A limit can cause thermal damage to the internal transistor arrays.

• External Power Supply: Ensure a stable 24 VDC power supply is connected to the external power terminals of the module. Since the module drives 64 points, a voltage drop on the external line can cause erratic behavior of the connected field devices. Use a dedicated industrial-grade power supply for I/O loads.

• Hot-Swap Safety: When hot-swapping the AH64AN02P-5C, ensure the latched connector is fully disengaged before pulling the module from the rack. When inserting the new module, press firmly until the locking tabs click into place to ensure a solid connection to the AH500 high-speed backplane.
