The SEL-3355 is a versatile computing platform built to withstand harsh environments in utility and industrial applications. The SEL-3355 can be configured as a Blueframe application platform or an industrial computer running a Microsoft Windows or Linux OS. For the related Real-Time Automation Controller (RTAC) model, see the SEL-3555.
The SEL-3355 is a powerful rack- or panel-mount computing platform featuring an Intel Xeon quad-core 2.0 GHz or 2.8 GHz processor. The SEL-3355 can be ordered from the factory with 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.
Blueframe—Improve your power system OT network management, simplify security patches, and ensure availability with SEL Blueframe application platform. You can configure SEL computing platforms (SEL-3350, SEL-3355, SEL-3360) with Blueframe to manage and operate SEL containerized applications, like the Data Management and Automation (DMA) applications.
Industrial Automation Platform—Deploy complete automation control and operator station functionality in a single package directly to the plant floor without the concern of environmental conditions. The SEL-3355 is a powerful and reliable computing platform that supports soft programmable logic controllers (PLCs) and operator HMI control engines. Design engineers can leverage virtual machine (VM) resources integrated into the chipset of SEL computing platforms to reduce project costs. SEL computing platforms are available with Xeon quad-core 2.0 GHz and 2.8 GHz processors to meet the needs of even the most demanding computing applications.
HMI Visualization, Monitoring, and Control—Make a secure system visualization, monitoring, and control point for your substation or plant. You can leverage CIS Security Benchmarks settings to meet NERC CIP and other industry compliance standards.
Information Processor: Data Concentrator/Protocol Converter—Collect and format relay data for legacy remote terminal units (RTUs), and send the data directly to SCADA systems using legacy protocols. You can leverage multiple paths for data access, collect data at one rate, and service them to any client via any supported protocol.
Centralized Authentication Server—Extend central authentication to your branch office or substation by logging in with enterprise credentials and using the same account throughout your network. You can set up role-based access controls and employ high-availability services for always-on service.
Original Equipment Manufacturer (OEM) Software Appliance—The SEL-3355 has the processing power and rugged hardware necessary for operating in critical infrastructure environments. Whether you are currently shipping a tough appliance or thinking about deploying your software as a dedicated appliance for rugged environments, consider the SEL-3355 to complement your solution.
Synchrophasor Archiver, Server, and Console—Install a single computing platform to concentrate, archive, and display synchronized phasor measurements from a wide area with SEL-5073 synchroWAVe Phasor Data Concentrator (PDC) Software. Implementing RAID capabilities provides the fastest and most reliable database storage.
Engineering Workstation—Meet or exceed IEEE 1613 and protective relay specifications for harsh environments with any SEL computing platform, made to withstand vibration, electrical surges, fast transients, and extreme temperatures. You can access the engineering workstation remotely and securely using Microsoft Windows Remote Desktop tunneled over IPsec or through Intel Active Management Technology (AMT) with remote KVM over IP.

Industrial and substation automation and computing systems require 24/7 availability and ease of service when necessary. In order to address these needs, SEL computing platforms employ “server class” reliability, availability, and serviceability (RAS) attributes.
SEL designs, manufactures, and tests every computing platform in house. Our computing platforms currently have an MTBF of over 300 years. And, SEL computing platforms are backed by a ten-year, no-questions-asked warranty.
Designed to keep your system operational for longer periods, the SEL-3355 can be optioned with dual load-sharing power supplies and a RAID-configurable four-bay SSD enclosure. The SEL-3355 includes either an Intel Core i7 multicore or a Xeon quad-core processor. SEL computing platforms also feature SEL’s unique system monitor (SysMon) with a watchdog timer.
Intel AMT allows you to view logs for evaluation and service even when the unit is powered off. You can reboot into another OS for diagnostics or to batch software and then bring the system back online, all remotely. Additionally, SEL’s SysMon logs events specific to the installed system to aid in quick recovery.
Robust Hardware Design
SEL computing platforms are designed for maximum reliability, with no fans or moving parts, and are backed by a ten-year warranty. The SEL-3355 has a durable power supply, an advanced thermal management system, error-correcting memory, and single-level cell (SLC) SSDs to provide reliable operation in the harshest environments.
Reliable Operation—Meets IEEE 1613, IEEE C37.90, and IEC 60255 Protective Relay Standards
Install the SEL-3355 in harsh environments. It is designed to withstand 15 kV electrostatic discharge, fast transients, radiated emissions, up to 15 g shock, seismic and sustained vibration, overcurrent, dielectric strength, and pulse magnetic field disturbances.
