ABB AI523 B8 Used Working AC500 Modules

Product Overview

The ABB AI523 (B8) is a high-performance analog input module from the AC500 PLC series. This module is designed for precision monitoring in industrial environments, offering 16 analog input channels that can be individually configured. Its versatility allows it to handle various signal types—including voltage, current, and temperature sensors (RTDs)—making it a flexible choice for complex process control. As a Used - Working unit, it provides a reliable, cost-effective way to maintain or scale your ABB control system with high-resolution data acquisition.

Key Features

• 16 Individually Configurable Channels: Each channel can be set to different input types (Voltage, Current, or RTD) via software.
• High Resolution: Features a 12-bit resolution (plus sign), ensuring precise digital representation of analog field signals.
• Multi-Signal Compatibility: Supports standard ranges: 0...10V, -10...+10V, 0...20mA, 4...20mA, and various PT/NI temperature sensors.
• Advanced Diagnostics: Includes comprehensive error detection, such as wire break and short-circuit monitoring, with a dedicated front-panel "ERR" LED.
• Fast Sampling: High-speed internal conversion allows for responsive monitoring of dynamic process variables.

Item Condition (Used/Working)

• Functional Status: This module has been professionally removed from a decommissioned AC500 system. It has been bench-tested to verify that the internal bus communication is active and analog-to-digital conversion is accurate across multiple channel configurations.
• Physical State: Shows standard industrial wear, including minor scuffs on the housing. All gold-plated backplane connectors and terminal interface pins are intact and clean.
• Visual Reference: Please refer to the high-resolution images to verify the specific Revision (B8) and manufacturing details; the unit pictured is the exact AI523 module you will receive.
• Note: Requires a compatible Terminal Base (e.g., TU515 or TU516) for installation and wiring.

Package Includes

1. 1 x ABB AI523 (B8) Analog Input Module
2. Note: Includes only the I/O module. The Terminal Base (TU), CPU, and software are not included.
