Product Description
Woodward SST-ESR2-CLX-RLL Ethernet ControlLogix Module
Product Overview
- The Woodward SST-ESR2-CLX-RLL is an Ethernet ControlLogix Module designed for interfacing Rockwell Automation ControlLogix programmable logic controllers (PLCs) with Ethernet-based industrial networks in power generation, industrial automation, and process control applications. This communication module, part of Woodward’s SST (SynchroNet Systems Technology) product line, enables seamless data exchange between ControlLogix PLCs and devices using Ethernet protocols, such as Modbus TCP, EtherNet/IP, or other industrial communication standards. The "CLX" indicates compatibility with the ControlLogix platform, and "RLL" refers to its integration with Rockwell’s Relay Ladder Logic programming environment. The module is ideal for integrating Woodward control systems (e.g., turbine or genset controllers) with PLC-based automation systems in power plants, marine applications, and industrial facilities. Compared to Woodward’s genset controllers (e.g., EasyGen-3500-5, 8440-2087), protection relays (e.g., XD1G11), or excitation systems (e.g., DECS-100-B15), the SST-ESR2-CLX-RLL is a communication interface, not a control or protection device. It is distinct from Woodward’s electronic governors (e.g., DYN1-10784-003-0-12), actuators (e.g., 8408-921), and other modules (e.g., 5466-1510 CPU).
