Allen-Bradley 5069-OW16 Relay Output Module

 

 

Product Overview

The Allen-Bradley 5069-OW16 is a 16-channel relay output module in the Compact 5000 I/O / CompactLogix 5380 system.

It is used to switch both AC and DC loads through mechanical relay contacts, making it more flexible than transistor or triac output modules.

Key Specifications

• Brand: Allen-Bradley (Rockwell Automation)
• Series: Compact 5000 I/O
• Model: 5069-OW16
• Channels: 16 relay outputs
• Output Type: Form A (Normally Open, dry contact)
• Voltage Range: 5–264 VAC / 5–125 VDC
• Load Type: AC or DC (universal contact switching)
• Contact Type: Electromechanical relay
• Isolation: basic isolation (not channel-to-channel isolated)
• Switching Delay: ~10 ms ON / OFF
• Channel Groups: 2 groups of 8 outputs (common grouping)
• Max Current: about 2 A per channel (resistive load)
• Module life: ~100k–300k cycles depending on load

Key Features

• 16 dry contact relay outputs (NO type)
• Can switch AC or DC loads freely
• No polarity limitation (unlike transistor outputs)
• Suitable for interposing relays, contactors, solenoids
• LED status indicators per channel
• Easy integration with Studio 5000 system

Working Principle

The PLC sends a signal → internal relay coil energizes → mechanical contact closes:

• PLC ON → relay closes → external circuit powered
• PLC OFF → relay opens → circuit disconnected

This provides electrical isolation between PLC and field devices.

Advantages

• Works with both AC and DC loads
• True “dry contact” output (very flexible wiring)
• No leakage current (unlike triac outputs)
• Safer for mixed industrial loads
• Easy troubleshooting (mechanical click + LED)
• Suitable for retrofit projects

Applications

• Control of contactor coils
• Solenoid valve switching
• Alarm systems
• Motor starter control circuits
• Signal switching (interposing logic)
• Industrial machine automation
