Allen-Bradley 1771-A4B 是一款通用 I/O 机箱

Allen-Bradley 1771-A4B 是一款通用 I/O 机箱，属于 1771 可编程逻辑控制器 （PLC） 产品系列。此机箱具有十六 （16） 个 I/O 插槽，用于托管电子电路，特别是背板，用于向连接的模块分配电源。它还承载现场接线臂的铰链。

1771-A4B 设计用于在 32-140 华氏度或 0-60 摄氏度的温度范围内运行，而硬件的存储温度为 -40 至 185 华氏度或 -40 至 85 摄氏度。它的相对湿度为5-95%，非冷凝。安装此通用 I/O 机箱时，请分别在 2-10 Hz 和 500g 下将面板振动和冲击保持在 15g 以内。

1771-A4B 能够通过 1771 处理器接收电源，该处理器带有提供 2-4 安培的集成电源、额定输出为 3-8 安培的电源模块和输出电流为 6.5-16 安培的外部电源。作为一般规则，切勿为 1771-A4B 安装外部电源和电源模块。此电源连接不兼容，将取消硬件配置的资格。

The Allen-Bradley 1771-A4B is a universal I/O chassis that belongs to the 1771 Programmable Logic Controller (PLC) product family. This case has sixteen (16) I/O slots for hosting electronic circuits, in particular a backplane for distributing power to connected modules. It also carries the hinge of the field connecting arm.

The 1771-A4B is designed to operate in a temperature range of 32-140 degrees Fahrenheit or 0-60 degrees Celsius, while the hardware has storage temperatures of -40 to 185 degrees Fahrenheit or -40 to 85 degrees Celsius. It has a relative humidity of 5-95% and is non-condensing. When installing this universal I/O chassis, keep panel vibration and shock within 15g at 2-10 Hz and 500g, respectively.

The 1771-A4B is capable of receiving power through the 1771 processor, which has an integrated power supply providing 2-4 amps, a power module rated for 3-8 amps, and an external power supply with an output current of 6.5-16 amps. As a general rule, do not install external power supplies and power modules for the 1771-A4B. This power connection is incompatible and disqualifies the hardware configuration.
