Allen-Bradley 1746-IH16 Digital Input Module
Manufacturer: Allen-Bradley (Rockwell Automation)
Product Number: 1746-IH16
Category: SLC 500 Digital Input Module
Number of Inputs: 16 points
Input Type: 24 V DC (sink/source)
Input Current: 7 mA at 24 V DC
Isolation: 1500 V AC optical isolation
Function: Acquires digital signals from field devices
Application: Industrial automation, discrete control, PLC input expansion
Product Description
The 1746-IH16 is a 16-point digital input module from Allen-Bradley, part of the SLC 500 series. This module provides current-sinking 125V DC inputs and is designed for use in both general-purpose and hazardous industrial environments (Class 1, Division 2). It offers reliable operation with a wide voltage range, drawing minimal power and ensuring effective isolation between inputs and control logic.
