SEL-2240
Axion
Coming Soon: Measure current from split-core CTs The Axion is a rugged, modular platform that combines the communications, built-in security, and IEC 61131 logic engine of the SEL Real-Time Automation Controller (RTAC) with a suite of I/O, monitoring, and control modules to provide high-speed, deterministic performance over an EtherCAT® backplane. The Axion supports multiple utility and industrial applications on a single device, while its modular construction supports decades of operation as well as seamless retrofits for legacy hardware. View the list of available Axion Modules.
One device with many uses
Combine Axion modules with the powerful RTAC logic engine to get more utility out of a single device. Use the Axion as a remote terminal unit (RTU), programmable logic controller (PLC), bay controller, digital fault recorder, SCADA data concentrator, phasor measurement unit (PMU), and substation gateway.
High-density, cost-effective I/O
Affordably manage thousands of devices, concentrate tens of thousands of data points, and minimize wiring by selecting the Axion modules that best suit your new or retrofitted installations. Connect hundreds of analog and digital I/O points on a single chassis, and connect up to six chassis in daisy-chain or star topologies.
Rugged, reliable, and secure by design
Install the Axion in the harshest environments, thanks to the –40° to +85°C (–40° to +185°F) operating range, up to 95 percent relative humidity resistance, and no moving parts. Optional redundant power supplies and a watchdog feature increase system reliability. RTAC module security features are optimized for operational technology (OT) environments.
Feature-rich hardware and software
Design an Axion with the exact features you need, including remote and/or local HMI on a 7" color touchscreen display, customizable bay control screens, programmable alarms, power quality measurements, 24 ksps fault recording, 3 ksps continuous waveform streaming, and a full range of supported protocols, including IEC 61850.

- Select from predefined bay screens or configure as many as 25 custom bay screens using the Bay Screen Builder application within acSELerator RTAC. Within the 25 screens, you can control over 100 elements, including breakers, two-position disconnects, and three-position disconnects. You can also view hundreds of analog and digital data in contextual displays.

- Stay informed using alarm functionality for the Axion Bay Controller touchscreen display. Create as many as 25 alarm panels, and customize aspects such as tile color and size, alarm messages, and flash operation. Use the intuitive Axion Bay Controller touchscreen to monitor and manage substation alarms onsite. An alarm summary screen provides a comprehensive overview of unacknowledged or active alarms.
