Descripción Reseñas

The Allen-Bradley 1746-IV8 is a high-performance discrete DC input module engineered for integration within the SLC 500 programmable controller platform. This module provides 8 current-sourcing input channels, specifically designed to interface with sinking-type (NPN) field devices such as proximity sensors, limit switches, and control pushbuttons. Its robust architecture ensures reliable signal acquisition in standard industrial automation environments.

Features

Eight (8) dedicated current-sourcing input channels.
Nominal input voltage of 24V DC with an operating range of 10 to 30V DC.
Integrated signal filtering with an 8 ms delay for both ON and OFF transitions to mitigate noise and contact bounce.
Front-panel LED indicators for each channel to facilitate rapid visual status monitoring and troubleshooting.
Compact SLC 500 form factor designed for efficient backplane mounting.

Applications

This module is ideal for industrial control systems requiring reliable 24V DC signal monitoring. It is frequently deployed in manufacturing lines, assembly machinery, and process control applications where sinking-type field sensors are utilized for logic input.
