Product Overview

The Allen-Bradley 1746-IC16 is a 16-point digital DC sinking input module from the SLC 500 series, manufactured by Rockwell Automation. Engineered for 48V DC general-purpose industrial control applications, it accepts 16 sinking inputs across a operating voltage range of 30 to 60V DC (at 55°C) or 30 to 55V DC (at 60°C). Utilizing a Removable Terminal Block (RTB) compatible with 1746-HT and 1746-HCA connectors, it draws 85 mA (0.085A) at 5V DC backplane power while weighing approximately 0.27 kg. Certified for Class 1, Division 2 (Groups A, B, C, D) hazardous locations, it delivers robust optical isolation and noise immunity for critical PLC input monitoring.

Key Advantages

  • High-Density 48V Sinking Design: Provides 16 discrete 48V DC sinking input channels in a single SLC 500 chassis slot for dense signal integration.
  • Class 1, Div 2 Hazardous Approval: North American standard rated for safe deployment in non-hazardous and Class 1, Division 2, Groups A, B, C, and D environments.
  • Removable Terminal Block (RTB): Simplifies initial wiring and system maintenance without disturbing existing field wiring connections.
  • 1500V AC Galvanic Isolation: Delivers dielectric withstand and isolation between input channels and backplane logic for high operational safety.
  • Lightweight SLC 500 Profile: Weighs approximately 0.27 kg for easy handling and low backplane power consumption.
