Product Overview
The 1756-A7XT from Allen-Bradley is a ControlLogix chassis featuring seven slots for modular automation systems. Each slot accommodates any compatible Bulletin 1756 module with slot guides and snap-on retention for secure installation.
Designed for horizontal back-panel mounting, the 1756-A7XT supports direct attachment of Bulletin 1756 power supply modules. Its backplane provides high-speed communication and reliable power distribution to each installed module.
Constructed for industrial use, this chassis withstands extreme temperatures from -13°F to 158°F (-25°C to 70°C) and relative humidity between 5% and 95% noncondensing. An advanced conformal coating enhances durability in ISA G3 environments.
The 1756-A7XT is ideal for panel-mounted installations, requiring a minimum cabinet size of 20 x 24 x 8 inches. Its robust design ensures longevity and seamless operation within a modular ControlLogix system.
