1756-A7 小型紧凑型机箱  电源安装插槽

【产品详情】

Allen-Bradley/Rockwell Automation 1756-A7 机箱是专为 Allen-Bradley ControlLogix 系统制造的小型紧凑型机箱。该机箱是市面上最小的 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 个分体式锁紧垫圈外，还需要 2 个星形垫圈。此外，如果该机箱没有 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 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（20 x 24 x 8 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 （8 AWG） 实心或绞合铜线，绝缘等级为 90 °C （194 °F） 或更高，而对于保护接地端子，合适的电线尺寸为 2.1 平方毫米 （14 AWG） 实心或绞合铜线，绝缘等级为 90 °C （194 °F） 或更高。

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

【英文介绍】

The Allen-Bradley/Rockwell Automation 1756-A7 chassis is a small, compact chassis built specifically for Allen-Bradley ControlLogix systems. The case is one of the smallest ControlLogix cases on the market, with only 2 mounting tabs on the top and 2 mounting tabs on the bottom. The 1756-A7 chassis 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 the 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 for 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 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 (20 x 24 x 8 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 grounding is 8.3 square mm (8 AWG) solid or stranded copper wire with an insulation class 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. Insulation class 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@ 1.2 VDC. 4A@ 3.3 volts DC; Chassis/slots are 15 A / 6 A@ 5.1VDC and 2.8A / 2.8A@ 24VDC.
