Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1794-IE8XT is an analog input module in Allen-Bradley's FLEX I/O-XT family. It provides eight single-ended analog input channels, each independently configurable for voltage (±10 V or 0…10 V) or current (0…20 mA or 4…20 mA). Conformally coated for extended-temperature operation (-20 °C to 70 °C), it interfaces via FlexBus and is intended for industrial process measurement and control, particularly in environments requiring extended temperature tolerance and field-economical modular I/O expansion. 1794-IE8XT is the extended-temperature variant of the 1794-IE8.
