  Product Description

  The Allen Bradley/Rockwell Automation 1756-A7 chassis is a small compact chassis designed specifically for the Allen Bradley ControlLogix system.This chassis is one of the smallest ControlLogix chassis currently available,with only 2 installation tabs at the top and 2 installation tabs at the bottom.The 1756-A7 chassis can be installed with or without 2 SEM screws,but if SEM screws are not used during installation,in addition to 2 flat washers and 2 open lock washers,2 star washers are also required.Additionally,if the chassis does not have SEM screws,4 Phillips screws are required,but if SEM screws are used,only 2 Phillips screws are required.The 1756-A7 chassis is an open device without a casing for protection.

  feature

  Supports up to 7 control modules

  Durable and sturdy structure

  Easy to install and maintain

  Compatible with various communication protocols

  Allen Bradley 1756-A7 is a seven(7)slot chassis for the ControlLogix Programmable Automation Controller(PAC)platform.This hardware is an important component of building a ControlLogix control system as a chassis,such as the 1756-A7,which provides backplane connections and allows modules to be installed in the provided module slots.

  The 1756-A7 also has a power installation slot located on the far left side of the chassis.This chassis supports ultra-thin,standard,and power supplies.

  The 1756-A7 is installed directly onto the sub panel of the cabinet through the four(4)mounting tabs provided.Its physical dimensions are 50.8 x 60.9 x 20.3 centimeters(20 x 24 x 8 inches),and its weight is approximately 1.10 kilograms(2.4 pounds).The overall size of 17560A7 may vary depending on the type of power supply used.The chassis is also equipped with functional grounding and protective grounding terminals.The recommended wire type and size for functional grounding is 8.3 square millimeters(8 AWG)solid copper wire or stranded copper wire,with an insulation grade of 90°C(194°F)or higher.For protective grounding terminals,the appropriate wire size is 2.1 square millimeters(14 AWG)solid or stranded copper wire,with an insulation grade of 90°C(194°F)or higher.

  The power consumption of the 1756-A7 ControlLogix chassis is 4.5 watts and provides a maximum backplane current supply of 1.5 A 1.2 VDC;4A 3.3 VDC;The chassis/slot is 15 A/6 A 5.1 VDC and 2.8 A/2.8 A 24VDC.

  The operating heat dissipation rate of 1756-A7 is 6.1 BTU/hour,and the maximum operating power rating is 1.8 watts.The backplane current of 1756-A7 is 2.8 A at 24 V,6 A or 15 A at 5.1 V,1.5 A at 1.2 V,and 4 A at 3.3 V.In addition,the shipping dimensions of the 1756-A7 chassis are 50.8 x 60.9 x 20.3 centimeters or 20 x 24 x 8 inches.It weighs 2.4 pounds.The measured operating temperature range is 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit.The recommended storage temperature range is-40 to 85 degrees Celsius.In addition,the humidity type compatible with 1756-A7 is non condensing,and the relative humidity level that the chassis can use is 5%to 95%.The impact level under working condition of the chassis is 30G(acceleration),while under non working condition,the impact level is 50G(acceleration).On the other hand,the 1756-A7 has an open housing that allows users to easily install.In addition,it also uses stranded or solid copper wire with a size of 8.3 square millimeters(14 AWG)(rated at 194 degrees Fahrenheit(90 degrees Celsius)or higher)for functional grounding,and wire with a size of 2.1 square millimeters(14 AWG)for protective grounding.

  application area

  The 1756-A7 A-B slot chassis is commonly used in various fields of industrial automation and control systems,including manufacturing,energy,and transportation.
