SEL3355 Computer

Industrial Computer Designed for Substations

Schweitzer Engineering Laboratories, Inc. has announced the SEL-3355, a high-performance, ruggedized, rack-mount computer, which is designed for  utility substations and other harsh environments that require highly reliable and highly available computing.

Designed around an Intel Core i7 multicore processor with up to 16 GB of error-correcting code (ECC) RAM memory, the SEL-3355 operates silently without fans or vents in temperatures ranging from –40° to +75°C. Additionally, it reliably operates in the presence of shock and vibration, electromagnetic interference, and electrostatic discharge. The SEL-3355 is SEL’s third-generation industrial PC and builds on a demonstrated reliability that is ten times that of typical industrial computers.

To address cybersecurity concerns, the SEL-3355 is available with tools to allow customers to implement Center for Internet Security (CIS) OS security benchmarks, thereby providing industry-agreed-to settings in the OS to improve the device security posture. In addition, Intel vPro technology includes several security measures designed into the chipset that make it less vulnerable to computer viruses and/or loss of sensitive information.

The SEL-3355 can be configured with dual hot-swappable power supplies, which can be connected to ac or dc power sources; up to four single-level cell (SLC) solid-state drives (SSDs) that can be configured with RAID redundancy to allow for drive replacement without loss of data; and SEL SysMon and Intel vPro™ technology that provide management of security, monitoring, diagnosing, and remote computer repair.
