Allen-Bradley 1793-IE4 Analog Input Module

The Allen-Bradley 1793-IE4 is a 4-channel analog input module designed for compact distributed I/O applications. It converts analog current or voltage signals from process sensors into 12-bit digital values for real-time processing by a central programmable logic controller (PLC). Featuring integrated screw terminal block connections, the module mounts directly onto a standard DIN rail to support local machine control and field signal acquisition.

Analog Signal Acquisition and Resolution

The module contains four analog input points with an internal 12-bit analog-to-digital converter (ADC). It handles continuous process measurements—such as pressure, flow, temperature, and level—converting variable field inputs into high-resolution digital data words transmitted across the system controller interface.

Mechanical Design and Wiring Setup

Designed for space-constrained enclosures, the unit features built-in screw terminals that accept individual channel wiring directly on the module body. It snaps onto standard 35 mm DIN rails without requiring a separate base unit, providing a self-contained layout for distributed automation panels.
