The SEL-3350 is a versatile computing platform built to withstand harsh environments in utility and industrial applications. The SEL-3350 can be configured as a Real-Time Automation Controller (RTAC), a Blueframe application platform, or an industrial computer running a Microsoft Windows or Linux OS.
The SEL-3350 is a cost-effective rack- or panel-mount computing platform featuring an Intel Atom quad-core 1.6 GHz processor. The SEL-3350 can be ordered from the factory with SEL RTAC, SEL Blueframe, Microsoft Windows 10 IoT Enterprise, or Microsoft Windows Server OSs preinstalled. SEL network and serial port drivers are also available to support the installation of third-party Linux OSs.
By using error-correcting code (ECC) memory and eliminating all moving parts, such as rotating hard drives and fans, SEL computing platforms achieve a mean time between failures (MTBF) of over 300 years. Designed, manufactured, and tested to the same standards as our protective relays, every SEL computing platform comes with our industry-leading ten-year warranty and is made in the U.S.A.
RTAC—Order the SEL-3350 as an RTAC for secure automation applications, such as a substation HMI or SCADA remote terminal unit (RTU) or for data concentration or event collection. For more information about the RTAC automation platform, its applications, and other available models, visit the RTAC platform page.
Blueframe—Improve your power system operational technology (OT) network management, simplify security patches, and ensure availability with SEL Blueframe application platform. You can configure SEL computing platforms (SEL-3350, SEL-3355, and SEL-3360) with Blueframe to manage and operate SEL containerized applications, like Data Management and Automation (DMA) applications.
Engineering Workstation—Choose an SEL computing platform as your engineering workstation platform to get a reliable and robust system suitable for the harshest environments. You can view and change IED settings, view report and event data, and easily access diagram drawings and documents onsite. Securely and remotely access the engineering workstation using a VPN, Microsoft Windows Remote Desktop, or Secure Shell (SSH).
Information Processor: Data Concentrator/Protocol Converter—Seamlessly and flexibly concentrate data and convert protocols with any SEL computing platform and a wide range of data concentration and protocol conversion software.
Kiosk—Select the SEL-3350 for remote user applications that require the power of a dedicated high-performance computer. With the option of a small 1U formfactor, the SEL-3350 packs the computing power your application needs into a limited space. Passive cooling and a wide temperature range mean it is possible to install SEL computing platforms in locations where off-the-shelf computers will not survive. With a projected mean time between failures (MTBF) of over 300 years, the SEL-3350 can operate with little or no maintenance, making it ideal for unattended operation.
HMI Visualization, Monitoring, and Control—Use the SEL-3350 to make a secure system visualization, monitoring, and control point for your substation or plant.

SEL designs, manufactures, and tests every computing platform in-house to ensure maximum reliability. There are no fans or moving parts in the SEL-3350, and it has a durable SEL power supply, passive thermal management system, error-correcting code (ECC) memory, and single-level cell (SLC) SSDs to provide reliable operation in the harshest environments.
We designed the SEL-3350 to withstand 15 kV electrostatic discharge, fast transients, conducted and radiated emissions, up to 15 g shock, seismic and sustained vibration, voltage surge, and large magnetic field disturbances. It meets IEEE 1613, IEEE C37.90, IEC 61850-3, and IEC 60255 protective relay standards. The SEL-3350 also meets IEC 61000-6-2 and IEC 61000-6-4 industrial environment standards. The SEL-3350 is designed to achieve a projected MTBF of over 300 years, ten times higher than that of a typical industrial computer. And, it is backed by a ten-year, no-questions-asked warranty.
For added protection, you can order the SEL-3350 with conformal coating to protect against harsh environments and airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture. Learn more about conformal coating.
Designed to keep your system operational for longer periods, the SEL-3350 includes a two-slot 2.5" SATA drive bay that can be loaded with solid-state drives (SSDs). SEL’s unique Microsoft Windows Management Infrastructure (MI)/Windows Management Instrumentation (WMI) interface and configurable alarm service, Backup and Recovery Tool (BaRT), and watchdog timer maximize system availability by alerting users of potential issues and minimizing downtime.
Users can perform diagnostics, change out drives (SSDs) and install software and operating systems. Additionally, SEL’s System Monitor (SysMon) logs events specific to the installed system to aid in quick recovery.
