Description

The Allen-Bradley 1746-IV8 is a modular DC input module designed for the SLC 500 programmable controller platform. It functions as an interface between field-side digital devices and the processor backplane, converting 24VDC current sourcing input signals into internal logic levels for execution within the control program. This discrete I/O module occupies a single slot in the SLC 500 chassis, integrating seamlessly into local or distributed I/O configurations.

The module features eight input points arranged in a single group, providing high-density signal acquisition for industrial automation tasks. Front-panel LED indicators display the real-time status of each individual I/O point, allowing maintenance personnel to quickly diagnose field wiring and signal state. Self-lifting pressure plate terminals accommodate secure wiring connections, supporting up to two 14 AWG wires per terminal to ensure robust mechanical and electrical integrity in high-vibration environments.

Features

  • Eight discrete current sourcing input points operating at 24VDC nominal voltage
  • Operating voltage range of 10 to 30VDC to accommodate fluctuating industrial power supplies
  • Backplane current draw of 50mA from the 5VDC rail and 0mA from the 24VDC rail
  • Maximum off-state voltage of 5VDC and maximum off-state current of 1mA for reliable noise immunity
  • Nominal input current of 8mA at 24VDC with a maximum signal delay of 8ms for both ON and OFF transitions
  • Front-panel status indicators providing clear visual feedback for each I/O channel

Applications

  • Discrete sensor signal processing from photoelectric switches, inductive proximity sensors, and limit switches
  • Status monitoring of industrial pushbuttons, selector switches, and auxiliary relay contacts
  • Interface telemetry for machine safety interlocks and run permissive chains
  • Data acquisition for local control panels and discrete manufacturing machinery
