The 2026 SEL Sales Meeting is underway, and day one was filled with learning, collaboration, and a shared focus on serving our customers.

The day began with perspectives from SEL leadership on the opportunities ahead and the importance of continuing to invest in people, technology, and innovation. Technical sessions throughout the day highlighted the depth of expertise across SEL, with discussions covering emerging challenges, evolving power system needs, and new solutions designed to help customers improve the safety, reliability, and resilience of their operations.

Attendees also had the opportunity to hear customer success stories, exchange ideas with colleagues, and explore new technologies during the Innovation Showcase. These conversations reinforced the value of working together, learning from one another, and staying focused on what matters most: helping customers solve their toughest challenges.

It was an energizing start to the week, and we’re looking forward to the discussions, connections, and opportunities still ahead.

Expand the serial capacity of an SEL Real-Time Automation Controller (RTAC) or an SEL Port Server by using the new SEL-2905 Serial Port Expander.

• Add 16 serial ports per expander, or scale up to 96 ports by connecting multiple SEL-2905 devices—managed by a single host.
• Expand serial capacity without adding IP-addressable devices.
• Operate in harsh utility environments, and rely on a ten-year warranty and no-cost technical support.
