Allen-Bradley 1794-IA8 Flex I/O AC Digital Input Module

Product Overview

The AB 1794-IA8 is an AC-powered Flex I/O digital input module designed for industrial applications. It provides 8 non-isolated discrete inputs with a nominal voltage of 120V AC. The compact module supports DIN rail or panel mounting and features an IP20 environmental rating, ensuring durability in standard industrial environments.

Engineered for reliability, the 1794-IA8 offers robust protection against voltage spikes and transient currents. Its low power dissipation and precise input measurement ensure consistent performance for discrete input monitoring. The module operates efficiently across a wide temperature range and withstands industrial vibration and shock conditions.
