1756-A7机箱是一款小巧紧凑的机箱，专为Allen-Bradley ControlLogix系统而设计。该机箱是可用的最小的ControlLogix机箱之一，顶部只有2个安装卡舌，底部只有2个安装卡舌。1756-A7机箱可以安装或不安装2个SEM螺钉，但如果安装时没有SEM螺钉，那么除了2个平垫圈和2个分锁垫圈外，还需要2个星垫圈。此外，如果此机箱没有SEM螺钉，则需要4个十字螺钉，但如果与SEM螺钉一起使用，则只需要2个十字螺钉。1756-A7机箱是开放式设备，没有用于保护的外壳。

Allen-Bradley 1756-A7是来自ControlLogix可编程自动化控制器(PAC)平台的七(7)插槽机箱。该硬件是将ControlLogix 控制系统构建为机箱的重要组件，例如1756-A7提供背板连接，并允许将模块安装在提供的模块插入插槽中。

1756-A7还装有电源的安装插槽，位于机箱的最左侧。此机箱支持超薄、标准和电源。

1756-A7通过提供的四(4)个安装卡舌直接安装到机柜的子面板上。它的物理尺寸为50.8 x 60.9 x 20.3厘米(20x24x8英寸)，重量约为1.10千克(2.4磅)。根据所使用的电源类型，17560A7的整体尺寸会有所不同。该机箱还配有功能性接地和保护性接地端子。功能接地的推荐电线类型和尺寸是8.3平方毫米(8AWG)实心或绞合铜线，绝缘额定值为90 °℃ (194 °F）或更高，而对于保护性接地端子，适当的电线尺寸为2.1平方毫米（14 AWG）实心或绞合铜线，绝缘额定值为90 °C (194°F)或更高。

1756-A7 ControlLogix机箱的功耗为4.5瓦，提供1.5A@1.2VDC的最大背板电流供应;4A@3.3伏直流;机箱/插槽为15A/6A@5.1 VDC和2.8A/ 2.8A@ 24VDC。

The 1756-A7 case is a small, compact case designed for Allen-Bradley ControlLogix systems. The case is one of the smallest ControlLogix cases available, with only 2 mounting tabs on the top and 2 mounting tabs on the bottom. The 1756-A7 case can be installed with or without 2 SEM screws, but if it is installed without SEM screws, then 2 star washers are required in addition to 2 flat washers and 2 split lock washers. In addition, if this case does not have SEM screws, four Phillips screws are required, but if used with SEM screws, only two Phillips screws are required. The 1756-A7 chassis is an open device with no protective housing.

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

The 1756-A7 also has a power supply mounting slot, located on the far left side of the case. This chassis supports ultrathin, standard, and power supplies.

The 1756-A7 is mounted directly to the sub-panel of the cabinet by means of the four (4) mounting latches provided. Its physical dimensions are 50.8 x 60.9 x 20.3 cm (20x24x8 in) and it weighs about 1.10 kg (2.4 lb). The overall size of the 17560A7 will vary depending on the type of power supply used. The case is also equipped with functional ground and protective ground terminals. The recommended wire type and size for functional ground is 8.3 square mm (8AWG) solid or stranded copper wire with an insulation rating of 90 ° C (194 °F) or higher, while for protective ground terminals, the appropriate wire size is 2.1 square mm (14 AWG) solid or stranded copper wire. The insulation rating is 90 °C (194°F) or higher.

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