Allen-Bradley 1794-IE8 8-Channel Analog Input Module

The Allen-Bradley 1794-IE8 FLEX I/O 8-Channel Analog Input Module provides eight isolated analog input channels for voltage or current signals in distributed industrial control systems. Designed for PLC-based automation, it accepts voltage signals up to ±10 V DC and current signals in 0–20 mA or 4–20 mA, delivering 16-bit resolution and transmitting accurate process data to the control system via the FLEX I/O backplane. With a backplane current draw of 40 mA at 5 V DC, it mounts on a FLEX I/O terminal base unit and features channel-to-backplane isolation for reliable remote monitoring in environments from 0 to 55 °C (32 to 131 °F). Common replacements include 1794-IF8, 1794-IT8, and 1734-IE8C, and the module is commonly applied in process control, manufacturing equipment, water and wastewater facilities, and automated production lines.
