The SEL-3530 is a mid-level rack- or panel-mounted model of the RTAC, available in 1U, 3U, or 1U half-rack form factors. Suitable for use in utility substations or industrial control and automation systems, the SEL-3530 provides complete and flexible system control with integrated security, unified logic, and reliability. This model is ideal for small to medium installations and applications integrating data for up to 60 devices.
For more information about the RTAC automation platform, its applications, and other available models, visit the RTAC platform page.
Rugged Hardware—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. For added protection, you can order conformal coating to protect against harsh environments and airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture. Learn more about conformal coating.
Simple, Seamless Configuration—Quickly design an integrated automation system that includes protocol conversion, SCADA communications, IEC 61850 integration, synchrophasors, time synchronization, data management, and programmable logic. New automation tools are continuously being added to simplify complex applications, such as condition monitoring, disturbance fault recording, configuring SCADA point maps, and archiving and alarming for data changes. See the acSELerator RTAC SEL-5033 Software manual for more information on our automation software extensions.
Extensive Protocol Support—Concentrate and manage data from new and legacy relays and other IEDs using our extensive set of protocols. Standard SCADA protocols are included with the purchase of any RTAC, including DNP3, IEC 60870-101/104, Modbus, and many more.
Integrated Security—The RTAC is built with cybersecurity from the hardware up. Exe-GUARD approvelist anti-malware technology provides increased security, making the RTAC the first product in the market to include an approvelist antivirus solution that does not require end-user patch updates. Make the RTAC the secure access point into your substation or plant with a full-featured set of engineering access tools. Authenticate using LDAP or RADIUS central authentication or local role-based user authentication. Restrict user access to the required set of functions to do the job with configurable role-based access control (RBAC). Log user activity in the Sequence of Events (SOE) log, and forward notifications via Syslog. Encrypt critical data and engineering access via Secure Shell (SSH) and Transport Layer Security (TLS). The RTAC enforces authentication and proxies engineering access connections for serial and LAN-connected devices.
Custom Logic— Create your logic solutions in the embedded IEC 61131 logic engine, which comes standard with every automation controller. Build custom user logic and access all system tags, including diagnostics, contact I/O, protocol data, and communications statistics, to provide unparalleled control flexibility.
Substation 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 most RTAC models and the SEL-2240 Axion. acSELerator Diagram Builder SEL-5035 Software easily maps the RTAC tag database to reduce screen development time.
