SEL-3350

Automation Controller

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. Discover why made in the U.S.A. is important.

Engineering Workstation—Choose an SEL automation controller as your engineering workstation platform to get a reliable and robust system suitable for the harshest environments. You can view and change IED settings, view report and event data, and easily access diagram drawings and documents onsite. Securely and remotely access the engineering workstation using a VPN, Microsoft Windows Remote Desktop, or Secure Shell (SSH).

Information Processor: Data Concentrator/Protocol Converter—Seamlessly and flexibly concentrate data and convert protocols with any SEL automation controller and a wide range of data concentration and protocol conversion software.

Kiosk—Select the SEL-3350 for remote user applications that require the power of a dedicated high-performance automation controller. With its small 1U formfactor, the SEL-3350 packs the computing power your application needs into a limited space. Passive cooling and a wide temperature range mean it is possible to install SEL automation controllers in locations where off-the-shelf computers will not survive. With a projected mean time between failures (MTBF) of over 300 years, the SEL-3350 can operate with little or no maintenance, making it ideal for unattended operation.

HMI Visualization, Monitoring, and Control—Use the SEL-3350 to make a secure system visualization, monitoring, and control point for your substation or plant.

Reliability

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.

Availability

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.

Serviceability

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.

OS Options

The SEL-3350 supports various OS installation options. The controller can be purchased as hardware without an OS installed, providing flexibility to install your own custom OS image.

The SEL-3350 supports computer configurations with factory-installed Microsoft Windows 10 IoT Enterprise and Windows Server OSs. SEL network and serial port drivers are available to support the installation of other third-party Linux OSs.

Third-party supported OS options:

Microsoft Windows 10 IoT Enterprise*
Microsoft Windows Server 2019 Standard*
Red Hat Enterprise Linus (RHEL)
CentOS Linux
Ubuntu LTS

Hypervisor supported options:

Microsoft Hyper-V
Linux KVM

More OS options coming soon!

In Q1, 2021, the SEL-3350 will include new configuration options including SEL’s Blueframe application platform and RTAC functionality.
