Product Overview

The Allen-Bradley 1756-OB16I 16-Channel Isolated Output Module is a high-performance digital output component for Rockwell Automation's ControlLogix ® platform. Engineered for mission-critical industrial automation, it features galvanic isolation between channels to prevent ground loops and voltage interference.

The module delivers robust 24V DC sinking outputs (0.5A per channel) with short-circuit protection and supports CIP Safety ™ protocol for functional safety compliance. Its hot-swappable design enables maintenance without system shutdown, while a built-in diagnostic LED per channel provides real-time status monitoring.

Constructed with an anodized aluminum housing and conformal-coated circuitry, it operates reliably in harsh environments with severe EMI/vibration exposure.

 
Critical Technical Specifications
  • Output Channels: 16 isolated sinking outputs (24V DC)
  • Current Capacity: 0.5A continuous per channel (8A total module) with ±0.1% accuracy
  • Isolation: 1500V AC channel-to-bus / 250V AC channel-to-channel
  • Response Time: ≤1ms (ON/OFF) with 2 μs synchronization via CIP Sync™
  • Surge Protection: 40A clamp (IEC 61000-4-5)
  • Voltage Range: 19-30V DC (operational) / 5-30V DC (signal)
  • Environmental: -40°C to +70°C / 5-95% non-condensing humidity
  • Certifications: UL 61010-1, ATEX/IECEx Zone 2, ISASecure EDSA Level 2
  • Communication: ControlNet™/EtherNet/IP™ via 1756 backplane (20 Mbps)
 
Targeted Applications
  • Energy Systems: Emergency shutdown (ESD) valve control in oil/gas refineries
  • Automotive Manufacturing: Robotic welding cell safety interlocks per ISO 13849
  • Chemical Processing: Solenoid-actuated dosing pump sequencing
  • Water Treatment: High-current actuation of sludge press valves
  • Material Handling: Conveyor emergency-stop circuit redundancy
  • Pharmaceutical: Isolator barrier system control with SIL 3 compliance
  • Power Generation: Turbine cooling fan activation during overload events
 
Competitive Advantages
  • Fail-Safe Integrity: Dual-wire FaultTolerant ™ architecture with IEC 61508 SIL 3 certification
  • Zero Downtime Maintenance: Hot Backup ™ redundancy with automatic channel failover
  • Smart Diagnostics: Predictive load monitoring alerts before contact degradation
  • Obsolescence Protection: Embedded FRAM memory retains data for 20+ years without batteries
  • Cyber Resilience: Diode-Level Port Security blocks unauthorized backplane access
  • Power Optimization: <1W per channel (65% less heat dissipation)
  • Total Cost Reduction: Eliminates external isolators - saves $2,000+ per cabinet
