SST-SR4-CLX-RLL 是 AB 罗克韦尔（Allen-Bradley）生产的一款高性能通讯模块，专为 Rockwell ControlLogix 系统设计，具有以下特性和功能：

多通道设计：每个 SR4 模块具备 4 个独立的 Modbus 串行通信通道，这些通道可以独立工作并彼此电绝缘，以实现与工业设备（如 Modbus 主站或从站）的强大数据交换。

支持多种协议：模块支持 Modbus 主/从 ASCII 和 RTU MODBUS TCP/UDP 客户端/服务器通信，适用于各种工业自动化应用。

远程配置和诊断：使用 EtherNet/IP 或 RSLinx 远程连接的控制台软件，可以节省配置和诊断时间。

易于集成：每个模块与其定制的 Add-On-Profile (AOP) 一起交付，易于集成在 RSLogix 5000 软件中。

数据传输模式：模块与 ControlLogix CPU 之间的输入/输出数据传输支持两种模式：“直接模式”，无需写入任何梯形逻辑，可共享达 248 输入字 + 248 输出字，或“分页模式”，可共享达 32,000 输入/输出字。

环境适应性：CLXT 模块能够承受高温，并能在严苛、腐蚀性的环境中工作，满足客户的各种应用要求。

灵活性和扩展性：模块支持更多的通信通道和协议，单个模块支持更多的通信通道和协议，直接输入/输出映射，无需写入梯形逻辑。

用户友好的配置工具：新的用户友好配置工具带有可视化循环功能屏幕，软件包配有先进的可视化诊断工具。

认证和兼容性：模块符合 CE、FM 认证 C、US Class 1 Div 2 – UL 1604 并符合 RoHS 标准，完全集成到 Rockwell Integrated Architecture Builder™ 和 ProsposalWorks™。

SST-SR4-CLX-RLL 通讯模块是工业自动化系统中理想的通讯设备，适用于需要高效、低成本网络解决方案的多种应用场景。

The SST-SR4-CLX-RLL is a high-performance communication module from AB Rockwell (Allen-Bradley) designed for Rockwell ControlLogix systems with the following features and functions:

Multi-channel design: Each SR4 module has four independent Modbus serial communication channels that can operate independently and electrically insulate each other to enable robust data exchange with industrial equipment such as Modbus master or slave stations.

Support for multiple protocols: Modules support Modbus master/slave ASCII and RTU MODBUS TCP/UDP client/server communication for a variety of industrial automation applications.

Remote configuration and diagnostics: Console software that uses EtherNet/IP or RSLinx to connect remotely saves configuration and diagnostics time.

Easy integration: Each module is delivered with its custom Add-On Profile (AOP) for easy integration in RSLogix 5000 software.

Data transfer mode: Input/output data transfer between the module and the ControlLogix CPU supports two modes: "Direct mode", which does not require writing any ladder logic and can share up to 248 input words + 248 output words, or "paging mode", which can share up to 32,000 input/output words.

Environmental adaptability: CLXT modules can withstand high temperatures and operate in harsh, corrosive environments to meet customer application requirements.

Flexibility and extensibility: Modules support more communication channels and protocols, single modules support more communication channels and protocols, direct input/output mapping, no need to write ladder logic.

User-friendly configuration tool: The new user-friendly configuration tool comes with a visual loop feature screen, and the package comes with an advanced visual diagnostic tool.

Certification and compatibility: Modules comply with CE, FM certification C, US Class 1 Div 2-UL 1604 and comply with RoHS standards. Full integration into Rockwell Integrated Architecture Builder™ and ProsposalWorks™.

The SST-SR4-CLX-RLL communication module is the ideal communication device for industrial automation systems, suitable for a variety of application scenarios requiring efficient and low-cost networking solutions.
