Brand: Allen-Bradley/Rockwell Automation
Series: ControlLogix
Part number： 1756-A7LXT Series
Product Type： ControlLogix-XT Chassis
The 1756-A7LXT conform-coated Allen-Bradley ControlLogix-XT chassis has seven slots and is designed to provide maximum durability in hazardous environments such as ISA G3 class hazardous environments. The maximum heat dissipation power of the chassis is 4.1 watts. "Per slot" backplane current levels are 1.5 volts DC 1.2 amps, 3.3 volts DC 4 amps, 5.1 volts DC 10 amps or 6 amps, and 24 volts DC 2 amps. The isolation voltage is determined by the installed power module. The 1756-A7LXT chassis is designed for horizontal mounting. The 1756-A7LXT chassis measures 50.8 x 60.9 x 20.3 cm and weighs about 1.1 kg. The case's North American temperature code is T5.

For protective grounding, it is recommended to use 14 AWG copper wire (solid or stranded) with a temperature rating of 90 degrees Celsius or higher. The case of the 1756-A7LXT chassis is open. The 1756-A7LXT chassis has an operating temperature of -13 to 140 degrees Fahrenheit and a storage temperature range of -40 to 185 degrees Fahrenheit. The air temperature around the 1756-A7LXT chassis should not exceed 140 degrees Fahrenheit. ESD immunity is 6 kV contact discharge and 8 kV air discharge. The 1756-A7LXT chassis is certified to FM, CE, RCM, KC and EAC standards. When used in a chassis with a standard power supply, the following spacing recommendations should be followed: The vertical distance between the top edge of the chassis and the chassis is 15.3 cm, the vertical distance between the two horizontally installed chassis is 15.3 cm, the vertical distance between the bottom edge of the chassis and the chassis is 5.1 cm, and the horizontal distance between two adjacent chassis is 7.7 cm.
