SEL-3355

Computing Platform

The SEL-3355 is a versatile computing platform built to withstand harsh environments in utility and industrial applications. It can run the hardened SEL Blueframe or SEL RTAC operating systems, run versions of Linux and Microsoft Windows, or run bare-metal or hosted hypervisors. Designed, manufactured, and tested to the same IEC standards as our protective relays, every SEL Computing Platform is backed by a standard worldwide, ten-year warranty.

Configure and order

Blueframe

Improve your power system operational technology (OT) network management, simplify security patches, and ensure availability with the 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 the Device 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 industrial computer 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.

SEL-3355 Details

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. Reliability
SEL designs, manufactures, and tests every computing platform in house. Our computing platforms have one of the highest MTBF ratings in the industry, and they are backed by a ten-year warranty. Availability
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. SEL computing platforms also feature the unique SEL system monitor (SysMon) with a watchdog timer. Serviceability
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 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. Wide-Range Power Supply
The power supply supports 120/240 Vac or 125/250 Vdc. You can choose two power supplies and use one with 120 Vac and the other with 125 Vdc for backup. Watchdog Functionality
Monitor and alarm for numerous system services and conditions with an embedded controller that provides an extra level of computer system reliability. The embedded controller includes a programmable system monitor interface and alarm configuration. High-Performance Intel Xeon Quad-Core Processors
The SEL-3355 features Intel multicore processors with Intel vPro technology and up to 64 GB of ECC RAM, providing the power you need for any application. Multiple I/O Ports
Directly connect to various local peripherals and high-speed network interfaces with two Ethernet ports, audio I/O, six USB 3.1 ports, three digital video ports, and two serial ports. Flexibility With PCI Slots
Four PCI Express and one legacy PCI expansion slots let you add additional serial ports, Ethernet ports, I/O, or other PCI Express cards that your application requires. Operating System Choices
You can purchase the SEL-3355 as hardware-only or configure it to run a variety of Linux and Microsoft Windows OSs to provide extreme flexibility and functionality along with enhanced security features. Large Storage Capacity
With a four-drive SSD bay, you can create one large volume or configure a typical RAID system that provides redundant and more reliable storage. The following SSD options are available:

SLC for the highest endurance and reliability
Pseudo-SLC (pSLC) for a higher capacity but reduced endurance
3D triple-level cell (TLC) for the highest capacity and a lower cost but reduced endurance
