Allen-Bradley 1794-IE12 Flex I/O Analog Input Module | 12-Channel

1794-IE12 Flex I/O High-Density Analog Input Module

Brand: Allen-Bradley (Rockwell Automation)
Catalog No.: 1794-IE12
Series: Flex I/O High-Density Analog Module

The 1794-IE12 is a 12-channel single-ended analog input module. It accepts 0-20 mA, 4-20 mA, ±10V DC, and 0-10V DC signals. The module uses successive approximation conversion with 16-bit resolution. It offers a conversion rate of 8.0 ms for all channels. Absolute accuracy is 0.1% full scale at 25 °C. This module is designed for the 1794-TB3G or 1794-TB3GS terminal bases. Keyswitch position 3 ensures correct installation. The 1794-IE12 is ideal for transmitters, indicators, and multi-loop controllers.
