The Allen-Bradley 1746-IV16 is a 24V DC sourcing digital input module designed for integration within the Allen-Bradley SLC 500 I/O chassis system. Featuring 16 sourcing input points sharing a single common, the 1746-IV16 interfaced module captures DC discrete signals from field sensors and switching devices to deliver accurate status feedback to the SLC 500 controller backplane.

Features

  • Equipped with 16 DC sourcing input points operating on a 24V DC voltage category.
  • Utilizes a single common line across all 16 channels.
  • Draws backplane current directly at 5V DC (85 mA) with 0 mA current consumption at 24V DC.
  • Features color-coded removable terminal blocks (RTB) for efficient field wiring maintenance.
  • Compatible with Bulletin 1492 pre-wired cable systems (1492-CABLEB) for direct interface module connection.

Applications

  • Digital sensor signal processing in SLC 500 industrial automation systems
  • Sourcing input interfaces for field switches, proximity sensors, and pushbuttons
  • Control panel discrete I/O rack integration
