1756-CN2RXT is a ControlLogix XT ControlNet redundant interface module. Rockwell identifies it as a 100-connection interface for the Logix XT platform.
Published XT environmental data includes a -25–70 °C operating range, -40–85 °C storage range, and 5–95% noncondensing relative humidity.
Use the exact ControlNet design, redundancy architecture, firmware, and environmental documentation for the installed system. The module does not make an incomplete network design redundant by itself.
