SEL-2240-Axion

The SEL-2240 Axion is a fully integrated, modular input/output (I/O) and control solution ideally suited for utility and industrial applications. It combines the communications, built-in security, and IEC 61131 logic engine of the SEL Real-Time Automation Controller (RTAC) family with a durable suite of I/O modules that provide high-speed, deterministic control performance over an EtherCAT network.

Whether your application calls for a remote terminal unit (RTU) or an ultrarugged programmable logic controller (PLC), the SEL-2240 will be a good match. All of the SEL Axion modules are rated from –40° to +85°C and can optionally include conformal coating. The system is designed to be flexible; use the right combination of modules and nodes in almost any arrangement to suit the job. The SEL-2244-3 Digital Output Module has substation duty contacts (30 A make, 6 A carry) in order to provide reliable operation and flexible application.

The SEL-3530, SEL-3530-4, SEL-3555 RTACs, and SEL-2241 RTAC Module can all operate as the CPU for an SEL Axion Platform. They interface seamlessly with the I/O modules and provide easy integration with other serial and Ethernet devices via preinstalled communications protocols. The RTACs also support multiple SCADA/HMI channels. For high-speed communication, use EtherCAT fieldbus connections to I/O modules or optional IEC 61850 GOOSE messaging with station IEDs.
