Bulletin 1756 ControlLogix-XT™ Extreme Environment Controllers function in the same way and offer the same features as the ControlLogix Standard Controllers. The XT controllers leverage the Rockwell Automation® Integrated Archi­tecture™ control engine with enhancements to meet the needs of extreme environment applications, including conformal coating that extends product life in harsh, corrosive environments. In addition, an XT control system spaces modules in every other slot for thermal cushion and offers redesigned ventilation for increased air flow.
