SEL-3355-2 Data Sheet
Schweitzer Engineering Laboratories, Inc.
2
peripherals, storage, video, audio, alarm, and serial I/O—all with protection against electrical shock
and surge.
➤
Power Supply.
The SEL-3355-2 supports two load-sharing, hot-swappable power supply modules,
enabling you to power the SEL-3355-2 from two independent power sources for maximum availability
and without needing to use inverters.
➤
Mass Storage.
The SEL-3355-2 supports four 2.5-inch SATA drives, which are hot-swappable and
accessible after removing the front drive-bay panel. High-performance, industrial-rated, solid-state
drives (SSD) are available as ordering options.
➤
RAID.
The integrated SATA controller supports Redundant Array of Independent Disks (RAID) con-
figurations to maximize data availability and improve storage volume performance.
➤
Display Interfaces.
DVI, DisplayPort, or HDMI video connections enable you to connect as many as
three simultaneous, independent, high-definition displays.
➤
Audio Interface.
Analog HD audio inputs and outputs enable connection to amplified speakers,
microphone, and audio sources for clear audible user feedback, audio capture and analysis, and voice
recognition. Digital audio can be streamed through the digital display interfaces for simple integration
and high-definition surround-sound.
➤
USB Connectivity.
The SEL-3355-2 has four rear-panel and two front-panel USB ports for connection
to a local keyboard, mouse, and any USB peripherals. Each port is individually current-limited, pro-
tecting the system from external short circuits, and enabling high-power devices such as USB hard
drives to be powered from any USB port.
➤
PCIe Expansion.
The SEL-3355-2 supports as many as four standard PCIe form-factor expansion
cards and one 32-bit PCI card, enabling you to customize the system I/O to meet your application
needs. Choose from a selection of SEL PCIe expansion cards or install your own custom, third-party
expansion card.
➤
Ethernet.
Two 10/100/1000 Mbps Ethernet port connections on the rear panel support high-speed net-
work connectivity and enable connections to independent networks or redundant paired network con-
nections. Network interface cards such as the SEL-3390E4 Quad-Gigabit Ethernet Card can be added
to the SEL-3355-2 for additional network connectivity.
➤
Serial I/O.
Two standard EIA-232 serial ports enable connection to adjacent electronic devices such as
automation controllers, communications radios, and modems. As many as four SEL-3390S8 Serial
Expansion Cards can be added to the SEL-3355-2 for applications that require many serial I/O connec-
tions and IRIG time synchronization and distribution.
➤
System Monitoring and Watchdog.
An embedded controller works in unison with the SEL SysMon
software to provide an extra level of automation controller system reliability and to detect failures in
the application software or operating system. The system logs any abnormal conditions, enables the
system alarm to alert operators of a problem, and, if necessary, can perform a self-restart to return to a
normal operating state.
➤
Alarm Contact Output.
SEL SysMon software controls the alarm contact output to signal in case of
system health problems or malfunctions. The Form C contact supports both normally open and nor-
mally closed alarm operation.
➤
Remote Management.
The SEL-3355-2 supports remote access over Ethernet by using Windows
Remote Desktop or Intel vPro Active Management Technology (AMT), enabling full access to system
video, keyboard, mouse, and storage.
