SEL-3355-2 Data Sheet
Improve Reliability, Availability, and
Serviceability With a Rugged Automation
Controller
The SEL-3355-2 Automation Controller uses a high-performance x86-64 architecture processor to support
modern operating systems like Microsoft Windows and Linux. The extremely rugged SEL hardware of the
SEL-3355-2 enables you to use your choice of automation controller operating system and software in very
harsh environments not suitable for general purpose computers.
Integrate the SEL-3355-2 in computing applications that demand high performance, reliability, and low
maintenance in extreme, harsh environments. The SEL-3355-2 offers a mean time between failure (MTBF)
of at least ten times that of typical industrial computers by eliminating all moving parts, including rotating
hard drives and fans; using high-quality solid-state drives; and using error-correcting memory technology. By
eliminating vent holes, the SEL-3355-2 significantly reduces dust buildup and foreign contaminants. Dual
modular, hot-swappable, ac/dc power supplies eliminate the need for external inverters and enhance system
reliability, availability, and serviceability. You can install software from SEL and third-party software ven-
dors to customize the SEL-3355-2 for your specific applications. Every SEL-3355-2 comes with the unprece-
dented ten-year, worldwide SEL warranty.
Major Features and Benefits
The SEL-3355-2 provides a rugged, easy-to-use automation controller platform for substation, industrial, or
other harsh environments.
➤
x86-64 Architecture.
The SEL-3355-2 uses the Intel Xeon E3 microprocessor architecture to deliver
very high performance and broad operating system and software compatibility. Multiple processor
cores and Intel Hyper-Threading Technology enable you to run multiple time-critical applications
simultaneously. Choose between 2.0 GHz and 2.8 GHz quad-core CPU options.
➤
Operating System Choices.
The SEL-3355-2 may be purchased as hardware only, or it may be pur-
chased with a variety of modern Microsoft Windows operating systems to provide added flexibility
and functionality along with enhanced security features.
➤
Form Factor.
The SEL-3355-2 is built on a 19” rack-mount chassis, designed for substation and
industrial control applications. The system includes rear-panel I/O connectors for linking to networks,
