Product Description
1756-IB16D - 16-Point 24VDC Isolated Input - Industrial Automation Rugged Hot-Swap Digital Module
Product Overview
The Allen-Bradley 1756-IB16D ControlLogix Digital Input Module delivers high-density 24V DC sinking/sourcing connectivity for mission-critical automation systems. Designed for Rockwell's ControlLogix platform, this 16-channel module features Class 1 Division 2 (HazLoc) certification and optical isolation between field/backplane circuits.
Its ruggedized design withstands voltage transients (5kV per IEC 61000-4-4) and operates reliably in -40 °C to +70°C industrial environments. With embedded diagnostics and electronic keying, it enables secure integration into Studio 5000® applications.
