Technical Specifications & Selection Guide

Selection Tip: The 1771-IVN is the preferred choice when your application requires high-density discrete input from 10-30V DC field devices within a PLC-5 or 1771 I/O architecture. For 120V AC input requirements, consider the 1771-IA series instead.

Core Features & Technical Advantages

• 32 Isolated DC Inputs — High-density I/O reduces chassis slot consumption and lowers overall system cost
• Wide Voltage Tolerance (10-30V DC) — Accommodates voltage fluctuations common in heavy-duty industrial environments
• Dual Sinking/Sourcing Compatibility — Supports NPN and PNP sensors without rewiring, maximizing field device flexibility
• Robust Channel Isolation — Channel-to-channel and channel-to-backplane isolation protects the PLC System from field-side faults
• Precision LED Diagnostics — Individual status indicators per point accelerate fault identification and reduce MTTR
• Seamless PLC-5 Integration — Drop-in compatible with all standard 1771 I/O chassis; no firmware updates required
• RSLogix Software Ready — Fully supported by Rockwell’s RSLogix 5 programming environment for rapid commissioning

Typical Application Scenarios

Oil & Gas Processing: Wellhead control panels and pipeline monitoring systems demand uninterrupted signal integrity. The 1771-IVN’s robust isolation architecture prevents ground loops from corrupting PLC inputs in electrically noisy field environments.

Automotive Assembly Lines: High-speed conveyor and robotic cell controllers require fast, reliable discrete input scanning. This module’s rapid response time ensures real-time feedback from proximity sensors and limit switches without cycle-time penalties.

Power Generation & Utilities: Turbine control and switchgear monitoring applications rely on proven, long-lifecycle components. As an Original New Allen-Bradley spare part, the 1771-IVN supports EOL legacy PLC-5 systems still operating in power plants worldwide.

Chemical & Pharmaceutical Plants: Process control loops in regulated industries require fully traceable, factory-certified components. Every 1771-IVN we supply comes with original manufacturer documentation to satisfy audit requirements.

Water & Wastewater Treatment: Remote I/O configurations in distributed treatment facilities benefit from the module’s stable performance across wide temperature ranges and its compatibility with existing 1771 chassis infrastructure.
