机箱适配器模块 1756-PSCA   冗余电源系统的重要组成部分

Allen-Bradley 1756-PSCA2 是一个机箱适配器模块，用于将电源从一个或两个冗余电源输送到机箱背板上的单个电源连接器中。它是构建 ControlLogix 冗余电源系统的重要组成部分。创建系统只需要其中之一，并且它与 Bulletin 1756-PA75R 和 1756-PB75R 电源兼容。

1756-PSCA2 冗余电源机箱适配器是一种开放式无源设备。它的电流容量为 1.5V DC 时 1.2 A、3.3V DC 时 4 A、5.1V DC 时 15 A 和 24V DC 时 2.8 A。

1756-PSCA2 机箱设计为水平安装。使用左侧的 1756-CPR2 电缆将其连接到电源。该电缆的弯曲半径为 5 英寸（12.7 厘米），这也是布线和连接零件的最小间隙。

1756-PSCA2 具有符合 EN 60079-15 和 IECEx UL 14.0008X 危险场所证书的 Ex nA IIC T4 Gc 保护类型。根据应用的接地要求将设备接地。某些应用可能需要额外的保护性接地端子螺柱，以将机箱连接到接地总线。为了尽量减少电阻，导线长度应尽可能短。

1756-PSCA2 机箱适配器模块是一种用于连接计算机机箱和外部设备的接口转换器。它可以将不同类型的接口转换为计算机机箱可以接受的接口。

1756-PSCA2 机箱适配器模块通常包括输入接口、转换电路、输出接口等部分。输入接口用于接收外部设备的接口信号，转换电路用于将输入接口的信号转换为计算机机箱可以接受的信号，输出接口用于将转换后的信号输出到计算机机箱中。

常见的机箱适配器模块包括 USB 转串口模块、PCI 转 PCIe 模块、SATA 转 SAS 模块等。它们具有不同的特点和应用场景，适用于不同的计算机机箱接口需求。

The Allen-Bradley 1756-PSCA2 is a case adapter module designed to transport power from one or two redundant power supplies to a single power connector on the backplane of the case. It is an important part of building the ControlLogix redundant power system. Only one of these is needed to create the system, and it is compatible with Bulletin 1756-PA75R and 1756-PB75R power supplies.

The 1756-PSCA2 redundant power case adapter is an open passive device. Its current capacity is 1.2A at 1.5V DC, 4 A at 3.3V DC, 15 A at 5.1V DC and 2.8 A at 24V DC.

The 1756-PSCA2 chassis is designed for horizontal installation. Connect it to the power supply using the 1756-CPR2 cable on the left. The cable has a bend radius of 5 inches (12.7 cm), which is also the minimum gap between wiring and connecting parts.

The 1756-PSCA2 has an Ex nA IIC T4 Gc protection type compliant with EN 60079-15 and IECEx UL 14.0008X Hazardous Place Certificate. Grounding the device according to the grounding requirements of the application. Some applications may require additional protective ground terminal studs to connect the case to the ground bus. In order to minimize resistance, the length of the wire should be as short as possible.

The 1756-PSCA2 Case adapter module is an interface converter used to connect a computer case to external devices. It can convert different types of interfaces into interfaces that the computer case can accept.

1756-PSCA2 chassis adapter module usually includes input interface, conversion circuit, output interface and other parts. The input interface is used to receive the interface signal of the external device, the conversion circuit is used to convert the signal of the input interface to the signal that the computer chassis can accept, and the output interface is used to output the converted signal to the computer chassis.

Common chassis adapter modules include USB to serial port module, PCI to PCIe module, and SATA to SAS module. They have different characteristics and application scenarios, and are suitable for different computer chassis interface requirements.
