The 1756-A10XT is a 10-slot ControlLogix extreme temperature chassis designed for use in harsh industrial environments where standard PLC hardware cannot operate reliably. It is part of the ControlLogix platform and provides mechanical housing, electrical backplane communication, and environmental protection for ControlLogix modules.
This chassis is engineered for applications exposed to extreme cold, heat, vibration, and humidity, making it suitable for outdoor installations, oil & gas sites, mining operations, and heavy industrial automation systems.
Unlike standard chassis, the XT series is specifically designed for extended environmental ranges while maintaining full compatibility with ControlLogix I/O, CPU, and communication modules.
