Designed as a server-class computer, the tough SEL-3355 Computer is built to withstand harsh environments in utility substations and industrial control and automation systems. By eliminating all moving parts, including rotating hard drives and fans, and using error-correcting code (ECC) memory technology, SEL computers have over ten times the mean time between failures (MTBF) of typical industrial computers. Designed, manufactured, and tested to the same standards as our protective relays, every SEL-3355 comes with an unprecedented ten-year, worldwide SEL warranty.

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. SEL rugged computers are powerful and reliable computing platforms that support soft programmable logic controllers (PLCs) and operator human-machine interface (HMI) control engines. Design engineers can leverage virtual machine (VM) resources integrated into the chipset of SEL computers to reduce project costs. The SEL computers are available with a 2.5 GHz (dual-core) or a 2.1 GHz (quad-core) Intel Core i7 processor 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. Leverage CIS Security Benchmarks settings to meet NERC CIP and other industry compliance.

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. 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. Set up role-based access controls, and employ high-availability services for always-on service.

Original Equipment Manufacturer (OEM) Software Appliance—Whether you are currently shipping a tough appliance, thinking about deploying your software as a dedicated appliance for rugged environments, or just at the idea stage, consider reselling the SEL-3355 with a custom overlay specially crafted for your business.

Synchrophasor Archiver, Server, and Console—Install a single rugged computing platform to concentrate, archive, and display synchronized phasor measurements from a wide area with SEL-5073 synchroWAVe Phasor Data Concentrator (PDC) Software. Implement RAID capabilities to provide the fastest and most reliable database storage.

Engineering Workstation—Meet or exceed IEEE 1613 and protective relay specifications for harsh environments with any SEL rugged computer, made to withstand vibration, electrical surges, fast transients, and extreme temperatures. 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.
