Product Overview

The Allen-Bradley 1734-IB4 is a 4-point sinking digital input module designed for distributed control systems using the POINT I/O architecture. Manufactured by Rockwell Automation, this module offers high-speed signal acquisition, compact design, and flexible configuration options for industrial automation environments.

Key Features

  • 4 sinking inputs grouped in a single block

  •  Wide operating voltage range from 10V to 28.8V DC

  • User-selectable input filter times for noise immunity

  • Tool-less installation with 1734-TB or 1734-TBS base assemblies

  •  LED indicators for input, module, and network status

  • Reinforced insulation tested at 2500V DC for 60 seconds

  • Low thermal dissipation for energy-efficient operation

  • Slim profile ideal for space-constrained panels
