Allen-Bradley 5069-IA16 Digital Input Module

 

 

Product Overview

The Allen-Bradley 5069-IA16 is a 16-channel AC digital input module for the CompactLogix 5380 / Compact 5000 I/O platform.

It is used to read industrial AC switch signals (120/240 VAC) from field devices and send them to the PLC for logic control.

Key Specifications

• Brand: Allen-Bradley (Rockwell Automation)
• Series: Compact 5000 I/O

Key Features

• 16 high-density AC input channels
• Supports both 120V and 240V AC signals
• Built-in LED status indicators per channel
• Fast integration with Studio 5000 system
• Compact DIN-rail modular design
• Field power monitoring (SA power concept)
• Designed for industrial noise environments

Working Principle

The module detects whether AC voltage is present at each input channel:

• AC present → input = “1” (ON)
• No voltage → input = “0” (OFF)

It continuously scans all 16 channels and sends a status word to the PLC CPU, which uses it in ladder logic.

Advantages

• High channel density (16 inputs in one module)
• Works with industrial AC control circuits directly
• Stable operation in noisy environments
• Easy diagnostics via channel LEDs + Studio 5000
• Reliable for OEM machine control systems
• Standardized Rockwell ecosystem integration

Applications

• Pushbutton and selector switch inputs
• Limit switches and safety interlocks
• AC relay feedback signals
• Motor starter auxiliary contacts
• Industrial machine control panels
• OEM automation systems
