Allen-Bradley 1794-IF8IH

Product Overview

The Allen-Bradley 1794-IF8IH is an 8-channel analog input module with integrated HART communication, part of the FLEX I/O platform. Designed for high-performance analog signal processing, each channel is individually isolated and supports analog devices with HART capabilities. It connects easily to distributed I/O systems via DIN rail and provides flexible integration in demanding industrial environments.

Key Highlights

• Total Channels: 8 analog inputs

• Isolation: Channel-to-channel isolation

• Protocol: HART-enabled for field device communication

• Voltage Supply: 24V DC

• Input Types: 4–20 mA current loop (HART compatible)

• Status LEDs for module and communication diagnostics

• Compact, modular I/O solution

• Hot-swappable when used with a compatible adapter

Detailed Specifications

• Part Number: 1794-IF8IH

• Input Range: 4–20 mA (HART)

• Resolution: 16-bit

• Isolation: Yes, per channel

• Power Supply: 24V DC (supplied through terminal base)

• Communication: Via FLEX I/O adapters (ControlNet, EtherNet/IP, etc.)

• Operating Temp: 0°C to 55°C

• Mounting: DIN rail with terminal base

• Certifications: UL, cUL, CE, ATEX, IECEx

• Enclosure Rating: Open-type

Common Uses

• Process control systems with HART field devices

• Distributed I/O applications in hazardous areas

• Refining, chemical, and pharmaceutical facilities

• Advanced analog signal acquisition

• Flow, pressure, and level measurement

Why It Stands Out

• Supports HART for smart device communication

• Individually isolated inputs improve signal integrity

• Compact, field-mountable design reduces panel space

• Integrates easily into existing FLEX I/O architecture

• Trusted Allen-Bradley quality and industrial durability
