Project Description

SEL-3555 Real-Time Automation Controller (RTAC)

SEL-3555 Real-Time Automation Controller (RTAC)
The fastest and most powerful Real-Time Automation Controller (RTAC) for advanced data concentration and control.

  • 55 times faster than other RTACs, providing powerful computing for large-scale automation projects.
  • Increases cybersecurity by using exe-GUARD™ whitelist antivirus technology to allow only authorized applications to run.
  • 1 ms deterministic processing intervals for time-sensitive protection and automation control.
  • Eliminates the need for a PC in the substation due to an integrated video port and easy-to-use HMI.

Powerful

Designed for the most advanced automation applications

  • 2.5 GHz dual-core or 2.1 GHz quad-core processor
  • Multicore processor complements the multithread IEC 61131 logic engine
  • 8 GB error-correcting code (ECC) RAM
  • Multiple high-resolution display interfaces for local HMI support

Reliable

Manufactured to operate in the harshest of environments

  • No fans, spinning drives, or moving parts to wear out
  • Designed to withstand operating temperatures of –40° to +75°C (dual-core) and –40° to +60°C (quad-core)
  • Reliable operation in the presence of vibration, seismic, and shock (15 g) events as well as large electromagnetic fi elds or RFI interference
  • Ten-year, no-questions-asked warranty

Secure

Designed for secure operation and access

  • SEL’s whitelist antivirus exe-GUARD technology to protect against malware and other cybersecurity threats
  • Individual and role-based accounts for configuration software and HMI operation
  • Centralized authentication through Lightweight Directory Access Protocol (LDAP)
  • Alerts via Syslog, text/email, and Sequence of Events (SOE) logging
  • Encryption of all Ethernet communications via SSH and SSL/TLS tunneling

Deterministic

Built for time-sensitive control applications

  • Configurable task cycle times as fast as 1 millisecond
  • Multiple processing threads with ability to prioritize every task
  • Diagnostics to help you manage and optimize all resources efficiently
