Allen-Bradley 5069-IB16 Digital Input Module

 

 

Product Overview

The Allen-Bradley 5069-IB16 is a 16-channel 24V DC digital input module for the CompactLogix 5380 / Compact 5000 I/O platform.

It is used to read ON/OFF signals from industrial field devices, such as:

• Push buttons
• Limit switches
• Proximity sensors
• Relay contacts

Key Specifications (verified)

• Brand: Allen-Bradley (Rockwell Automation)
• Series: Compact 5000 I/O
• Model: 5069-IB16
• Channels: 16 digital inputs
• Input Type: 24V DC sinking input
• Input Voltage Range: typically 10–32 VDC
• Signal Type: DC discrete (ON/OFF)
• Isolation: channel group sharing common (not individually isolated)
• Platform: CompactLogix 5380 / GuardLogix 5380
• Mounting: Compact 5000 chassis / DIN rail system

Key Features

• 16 high-density DC digital inputs
• 24V industrial standard compatibility
• LED status indicators per channel
• Fast response for machine control
• Easy integration with Studio 5000
• Stable performance in industrial environments

Working Principle

The module detects presence of 24V DC signal:

• 24V applied → input = “1” (ON)
• 0V / open circuit → input = “0” (OFF)

PLC reads all 16 channels as a digital input word for logic control.

Advantages

• Simple and reliable signal acquisition
• Widely compatible with industrial sensors
• Low wiring complexity
• Fast response time
• Cost-effective high-density input solution
• Strong Rockwell system integration

Applications

• Machine automation systems
• Conveyor control systems
• Sensor signal acquisition
• Motor status feedback
• Industrial control panels
• OEM equipment

Important Precautions

•  
• Must use correct wiring type:
  • sinking (NPN) configuration required
• Common issues if miswired:
  • all inputs stay OFF
  • no LED response
  • incorrect PLC reading
• Do not mix:
  • AC signals
  • voltage above 32V
• Ensure correct:
  • field power (24VDC stable supply)
  • proper grounding and shielding for long cables
