Engineering Access and SCADA—Deploy the RTAC as a data concentrator using protocols such as IEC 61850 MMS client, Modbus, DNP3, IEC 61850 GOOSE, LG 8979, IEC 60870-5-101/104, or Mirrored Bits communications, and integrate both serial and Ethernet intelligent electronic devices (IEDs). Enable logging on any system or IED tag to view and archive station-wide event records. Enable multiple SCADA connections via serial or Ethernet communications.
Distribution Automation—Improve the reliability and reduce the cost of a distribution system by commissioning the RTAC as a Distribution Automation Controller (DAC). A DAC provides wide area Automatic Network Reconfiguration to minimize outage size and area by isolating faults and restoring power to un-faulted areas. It also provides Dynamic Feeder Optimization functionality, which allows distribution tap changers, voltage regulators, and capacitor banks to work together as a team to control power factor and reduce voltage.
Substation Human-Machine Interface (HMI)—Provide cost-effective local and remote monitoring, control, and annunciation for substations and other processes by installing the optional web-based HMI, available for the RTAC and SEL-2240 Axion. acSELerator Diagram Builder SEL-5035 Software easily maps the RTAC tag database to reduce screen development time.
Secure Communications and User Management—Employ the RTAC, SEL-3620 Ethernet Security Gateway, and SEL accessories to secure your automation network. Per-user security profiles provide compliance with role-based requirements. The system supports intrusion detection, notification, and logging to help maintain perimeter integrity. Secure Shell (SSH) and password management provide encrypted engineering access through the RTAC.
Make the RTAC the secure access point into your substation or plant using Lightweight Directory Access Protocol (LDAP) central authentication, local role-based user authentication, access logs, and secure engineering access. This increases your system security and helps meet regulatory standards.
Simple, Seamless Configuration
Quickly design an integrated automation system that includes protocol conversion, SCADA communications, synchrophasors, time synchronization, data management, and programmable logic. See how easy it is to set up and start using the SEL RTAC with our "how to" video series.
Renowned SEL Reliability and Support
The RTAC is designed and tested to meet or exceed IEEE 1613 and protective relay specifications for harsh environments and to withstand vibration, electrical surges, fast transients, and extreme temperatures. The SEL RTAC operates reliably, even in challenging environments.
Optional Web HMI
Create web-based HMI one-line diagrams, annunciator screens, and control scheme visualizations with optional acSELerator Diagram Builder SEL-5035 Software. Understand and visualize system status and configuration at the substation or anywhere you have network access.
