Product Description

The Allen-Bradley 1794-IF8IH module is a Flex I/O 8CH analog input module designed for industrial automation. It features eight isolated analog input channels, supporting current (0–20 mA, 4–20 mA) or voltage (±10 VDC, 0–10 VDC) signals, with 16-bit resolution. This module interfaces directly with Flex I/O backplanes and supports RS-485-based networks via 1794 adapter modules. Operating within 10–30 VDC, it functions reliably in temperatures from -20°C to 70°C. Ideal for process control, manufacturing, and harsh environments, the 1794-IF8IH offers high noise immunity and diagnostic capabilities, though configuration requires compatible software. It lacks integrated battery or display components, focusing on robust signal acquisition. Typical applications include monitoring sensors, variable-speed drives, and pressure/flow systems requiring precise analog data integration.
