SEL-3350 Автоматжуулалтын контроллёр

The SEL-3350 is a versatile controller ideal for dedicated embedded applications that require midlevel I/O and computation. It is a great fit for panels with limited rack space and users who are looking for a hardened, cost-effective yet flexible controller to run their choice of OS. The SEL-3350 can be configured to run Microsoft Windows and Linux OSs. Designed, manufactured, and tested to the same standards as our protective relays, the SEL-3350 withstands the harsh environments in utility substations, industrial control systems, and automation systems; comes with an industry-leading ten-year warranty; and is made in the U.S.A.


SEL designs, manufactures, and tests every automation controller 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 computer events specific to the installed system to aid in quick recovery.
