Complete a Five-Minute Upgrade and Get Five Times the Power
Watch how easy it is to upgrade your SEL-2240 Axion.

In less than five minutes, you can get five-times more processing power for your Axion by upgrading your existing Real-Time Automation Controller (RTAC) module to the new SEL-2241-2 RTAC Module. This enhanced performance supports a wide range of applications, such as data concentration, substation bay control, digital fault recording, and power system monitoring.
Upgrade your Axion to:
- Double the EtherCAT®* bandwidth to support additional Axion I/O modules.
- Capture every disturbance with a digital fault recorder solution that supports continuous waveform streaming at 3 kilosamples per second.
- Access new technologies, such as monitoring power system harmonics and streaming synchrophasors at data rates up to 120 messages per second.
- Support a reliable, long-term control and monitoring solution with the Axion, which comes with a ten-year product warranty.
Upgrade your hardware without rewiring.
Install the powerful SEL-2241-2 RTAC Module directly on the Axion backplane using a single retaining screw. The installation process:
- Replaces any legacy SEL-2241 RTAC Module.
- Reduces the need for cable rework.
- Minimizes system downtime.
Convert your project settings in five steps.
Use our RTAC software project conversion tool to easily transfer project settings to the new SEL-2241-2 RTAC Module. The project conversion tool:
- Includes a point-and-click user interface.
- Seamlessly migrates settings.
- Eliminates the need to retrain users.
