FAQ

• What does "XT" stand for?
  XT stands for "Extended Temperature." This product line is specifically designed for harsh environments with wide temperature ranges and challenging conditions.
• Can I use this controller in a standard ControlLogix chassis?
  It is designed for use with compatible XT-series chassis (e.g., 1756-A7LXT). Using it in a standard chassis may not provide the same environmental protection.
• What is the main advantage over a standard L63 controller?
  The primary advantage is the extended operating temperature range (-25°C to 70°C) and conformal coating, making it suitable for outdoor or harsh indoor applications.
