1756-A4 提供高速通信路径 ControlLogix 机箱

【产品详情】

Allen-Bradley 1756-A4 是一款带有四 （4） 个插槽的 ControlLogix 机箱。该机箱用于容纳 ControlLogix 并包含合作伙伴模块，并通过提供的电子电路提供背板电源，该电路也用作本地总线连接。重量 0.75 千克（1.7 磅），尺寸为 50.8 x 50.8 x 20.3 厘米（20 x 20 x 8 英寸）。

Allen-Bradley 1756-A4 是 ControlLogix 机箱。它是一款 4 插槽 ControlLogix 机箱，具有功耗和 1.8 W 功耗。它的尺寸为 50.8 x 50.8 x 20.3 厘米（20 x 20 x 8 英寸）。重 1.7 磅。它水平安装在面板内部，并具有开放式外壳。它的最大背板电流为 1.5 A（1.2 V DC）、4 A（3.3 V DC）、15 A（5.1 V DC）和 2.8 A （24 V DC）。

机箱背板在模块之间提供高速通信路径，并将电源分配给机箱内的每个模块。

1756-A4 标准机箱具有带电拆卸和插入 （RIUP） 功能，易于维护。为了防止更换错误，它还提供电子键控。

1746-A4 是 Allen-Bradley ControlLogix 机箱，可安装在 ControlLogix 模块、处理器、IO 模块、通信适配器、专用模块、智能模块、包含合作伙伴模块和第三方模块上。

1746-A4 具有四 （4） 个插槽。除了提供模块安装插槽外，此机箱还包含电子背板，背板电源分配到该背板，为连接到单个机箱插槽的任何模块供电。

机箱还提供系统电源的安装方式。由于电源通过提供的电源接口安装在机箱外部，因此系统电源不包括在插槽计数中。作为四 （4） 插槽机箱，最低额定 ControlLogix 电源能够为连接到它的模块供电。

ControlLogix 机箱还支持分布式应用程序。对于分布式应用程序，I/O 模块可以安装在处理器远程的机箱上。这样可以防止安装单独的信号电缆本垒打。对于分布式应用程序，分布式 I/O 通道没有处理器，而是与所需的 ControlLogix 模块一起安装通信适配器。ControlLogix 系统内的任何机箱都可以用作分布式 I/O 机箱，包括 1756-A4。每个机箱都需要一个单独的系统电源。

ControlLogix 机箱附带其他机箱变体，包括 1756-A7、1756-A10 和 1746-A13 和 1756-A17。

【英文介绍】

The Allen-Bradley 1756-A4 is a ControlLogix chassis with four (4) slots. The case is used to house the ControlLogix and contains the partner module, and provides backplane power through the supplied electronic circuit, which also serves as a local bus connection. It weighs 0.75 kg (1.7 lb) and measures 50.8 x 50.8 x 20.3 cm (20 x 20 x 8 in).

Allen-Bradley 1756-A4 is a ControlLogix chassis. It is a 4-slot ControlLogix case with power consumption and 1.8W power consumption. It measures 50.8 x 50.8 x 20.3 cm (20 x 20 x 8 inches). It weighs 1.7 pounds. It is mounted horizontally inside the panel and has an open housing. Its maximum backplane currents are 1.5 A (1.2 V DC), 4 A (3.3 V DC), 15 A (5.1 V DC), and 2.8 A (24 V DC).

The chassis backplane provides high-speed communication paths between modules and distributes power to each module in the chassis.

The 1756-A4 standard chassis features live Removal and insertion (RIUP) for easy maintenance. To prevent replacement errors, it also offers electronic keying.

The 1746-A4 is an Allen-Bradley ControlLogix chassis that can be installed on ControlLogix modules, processors, IO modules, communication adapters, dedicated modules, smart modules, inclusive partner modules, and third-party modules.

The 1746-A4 has four (4) slots. In addition to providing module mounting slots, this case also contains an electronic backplane to which backplane power is allocated to power any module connected to a single chassis slot.

The chassis also provides installation methods for the system power supply. Since the power supply is installed outside the case through the provided power interface, the system power supply is not included in the slot count. As a four (4) slot case, the lowest rated ControlLogix power supply is capable of powering modules connected to it.

The ControlLogix chassis also supports distributed applications. For distributed applications, I/O modules can be installed on a chassis remote from the processor. This prevents the installation of separate signal cables for home runs. For distributed applications, the distributed I/O channel does not have a processor, but instead installs a communication adapter along with the required ControlLogix module. Any chassis within the ControlLogix system can be used as a distributed I/O chassis, including the 1756-A4. Each case requires a separate system power supply.

The ControlLogix chassis comes with other chassis variants, including the 1756-A7, 1756-A10, and 1746-A13 and 1756-A17.
