The SEL-3530 Real-Time Automation Controller (RTAC) is available in 1U, 3U, or 1.5U rack-mount and panel-mount versions. We offer remote or field installation and commissioning services for SEL products.
The SEL-3530 is a mid-range rack-mount or panel-mount RTAC available in 1U, 3U, or 1.5U form factors.
Suitable for utility substations or industrial control and automation systems, the SEL-3530 provides complete, flexible system control with integrated security, unified logic, and reliability. This model is ideal for small to medium-sized installations and applications integrating data from up to 60 devices.
Key features of the SEL-3530 Real-Time Automation Controller include: Robust Hardware – The RTAC is designed and tested to meet or exceed IEEE 1613 and protection relay specifications, making it suitable for harsh environments and able to withstand vibration, surges, fast transients, and extreme temperatures.
Even in challenging environments, the SEL RTAC operates reliably.
For additional protection, you can order conformal coatings to protect against harsh environments and air pollutants such as hydrogen sulfide, chlorine, salt, and moisture.
Simple, seamless configuration—quickly design an integrated automation system, including protocol conversion, SCADA communication, IEC 61850 integration, phasor synchronization, time synchronization, data management, and programmable logic.
Continuously adding new automation tools to simplify complex applications such as condition monitoring, interference and fault logging, configuring SCADA point maps, and archiving and alarming data changes. For more information on our automation software extensions, please refer to the acSELerator RTAC SEL-5033 software manual.
Extensive protocol support—centralize and manage data from new and legacy relays and other IEDs using our extensive protocol set. Standard SCADA protocols are included with any RTAC purchase, including DNP3, IEC 60870-101/104, Modbus, and more.
Our company offers the SEL-3530 Real-Time Automation Controller (RTAC) from the USA.
We source directly from SEL, ensuring genuine SEL-3530 RTAC controllers, which also feature the following characteristics: Comprehensive Security—RTAC establishes network security from the hardware level.
Exe-GUARD approvelist anti-malware technology provides enhanced security, making RTAC the first product on the market to include an approvelist antivirus solution that does not require end-user patch updates. A full suite of engineering access tools makes RTAC a secure access point for substations or plants.
Authentication is performed using LDAP or RADIUS central authentication or local role-based user authentication. Configurable role-based access control (RBAC) restricts user access to the necessary set of functions to complete tasks.
User activity is logged in the Event Sequence (SOE) log, and notifications are forwarded via the system log.
Critical data and engineering access are encrypted via Secure Shell (SSH) and Transport Layer Security (TLS). Custom Logic—Create your logic solution within the embedded IEC 61131 logic engine, a standard configuration for every automation controller.
Build custom user logic and access all system tags, including diagnostics, contact I/O, protocol data, and communication statistics, to provide excellent control flexibility.
Substation HMI—Provide cost-effective local and remote monitoring, control, and notification for substations and other processes by installing an optional web-based HMI, applicable to most RTAC models and the SEL-2240 Axion.
The acSELerator Diagram Builder SEL-5035 software easily maps the RTAC tag database to reduce screen development time.

Plain language sourcing guide for American SEL-3530 Real-Time Automation Controller (RTAC)
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
