Allen-Bradley 1756-L73S 可编程自动化控制器  具有执行标准

【产品详情】

1756-L73S 是一款 Allen-Bradley GuardLogix 5570 可编程自动化控制器 （PAC）。该控制器具有执行标准和安全功能的能力。标准功能由控制器本身执行，而安全功能则单独传达给目录号为 1756-L7SP 的合作伙伴控制器。此主控制器是启用 GuardLogix 控制器安全功能所必需的，并且必须安装在 1756-L73S 旁边的直接可用插槽中。

1756-L73S 配备 8 MB 标准用户内存、4MB 安全内存和 0.98 MB I/O 内存。它随附 1756-SD1 安全数字 （SD） 卡，内存容量为 1 GB 非易失性存储器。1756-L71S的嵌入式通讯口为单个USB通讯口，只能用于编程、硬件配置和在线编辑，不能用于工业通讯。凭借嵌入式存储器功能，1756-L73S 最多支持 128,000 个离散 I/O 点和 4000 个模拟 I/O 点。

1756-L73S 是一款环保处理器，因为它安装了 1756-ESMCAP 电容器储能模块，该模块可拆卸并预装在每个控制器中。它可以替换为 1756-ESMNSE 或 1756-ESMNRM。所有这些储能模块都是基于电容器的，无需锂电池。

1756-L73S 与适当的合作伙伴控制器一起使用时，已通过 SIL 3 和 PLe 认证，与类似安全等级的应用兼容。标准控制器功能可以使用继电器梯形逻辑 （RLL）、结构化文本、功能块图、顺序功能图 （SFC） 进行编程，而对于安全任务，只允许使用继电器梯形逻辑。

安全合作伙伴控制器可自动配置，为单个项目带来重大优势。它具有更强的运动处理能力和速度以及高性能逻辑。它有一个用于通信的 USB 端口。它最多可支持 500 个控制器连接。1756-L73S 控制器具有 8MB 用户内存、4MB 安全内存和 0.98MB I/O 内存。它可以支持 128,000 个数字 I/O 和 4000 个模拟 I/O。它在 1.2V DC 时消耗 5mA 的电流，在 5.1V DC 时消耗 800mA 的电流。其功耗为 2.5W，散热为 8.5 BTU/hr。它重 0.55 磅，具有 30V（连续）的隔离电压，用于基本绝缘。它可以安装在 ControlLogix 1756 机箱的任何插槽中，也可以在同一机箱中安装多个控制器。为了安全通信，它使用 ControlNet、DeviceNet 或 Ethernet/IP 网络。1756-L73S 控制器可以通过背板或 I/O 链路控制或监控 I/O。对于控制器诊断，它有一个提供运行时信息的前显示屏。它使用储能模块，这意味着不需要锂电池。预装了 1 GB （1784-SD1） 安全数字卡作为可选的非易失性存储器，可扩展至 2 GB （1784-SD2）。

【英文介绍】

The 1756-L73S is an Allen-Bradley GuardLogix 5570 programmable automation controller (PAC). The controller has the ability to perform standard and safety functions. Standard functions are performed by the controller itself, while safety functions are communicated separately to the partner controller with catalog number 1756-L7SP. This master controller is required to enable the GuardLogix controller security features and must be installed in a directly available slot next to the 1756-L73S.

The 1756-L73S comes with 8 MB of standard user memory, 4MB of safe memory, and 0.98 MB of I/O memory. It comes with a 1756-SD1 secure digital (SD) card with a memory capacity of 1 GB of non-volatile memory. The 1756-L71S embedded communication port is a single USB communication port, which can only be used for programming, hardware configuration and online editing, and cannot be used for industrial communication. With embedded memory capabilities, the 1756-L73S supports up to 128,000 discrete I/O points and 4,000 analog I/O points.

The 1756-L73S is an environmentally friendly processor as it is fitted with the 1756-ESMCAP capacitor energy storage module, which is removable and pre-installed in each controller. It can be replaced with 1756-ESMNSE or 1756-ESMNRM. All of these energy storage modules are based on capacitors and do not require lithium batteries.

The 1756-L73S are SIL 3 and PLe certified when used with appropriate partner controllers and are compatible with applications with similar safety levels. Standard controller functions can be programmed using relay ladder logic (RLL), structured text, function block diagrams, sequential function diagrams (SFC), while for safety tasks, only relay ladder logic is allowed.

Security Partner controllers can be configured automatically, providing significant benefits to individual projects. It has greater motion processing power and speed as well as high-performance logic. It has a USB port for communication. It supports up to 500 controller connections. The 1756-L73S controller has 8MB of user memory, 4MB of security memory, and 0.98MB of I/O memory. It can support 128,000 digital I/ OS and 4,000 analog I/ OS. It consumes 5mA of current at 1.2V DC and 800mA at 5.1V DC. It has a power consumption of 2.5W and a heat dissipation of 8.5 BTU/hr. It weighs 0.55 pounds and has an isolation voltage of 30V (continuous) for basic insulation. It can be installed in any slot in the ControlLogix 1756 case, or multiple controllers can be installed in the same case. For secure communication, it uses ControlNet, DeviceNet, or Ethernet/IP networks. The 1756-L73S controller can control or monitor I/O through a backplane or I/O link. For controller diagnostics, it has a front display that provides runtime information. It uses energy storage modules, which means there is no need for lithium batteries. A 1 GB (1784-SD1) secure digital card is pre-installed as an optional non-volatile memory, expandable up to 2 GB (1784-SD2).
