AcSELerator RTAC 1.155.201.6000

AcSELerator RTAC Editor's Review

AcSELerator RTAC from Schweitzer Engineering Laboratories is a high-performance remote terminal and automation controller engineered for utility and industrial power systems. The platform combines protocol bridging, sequence-of-events processing, programmable logic, and secure communications to centralize control, automate protection actions, and simplify system integration across substations and distributed assets.

Key capabilities

• Protocol and systems integration: Native support for industry-standard protocols such as DNP3 and Modbus, plus IEC 61850 interoperability, lets RTAC act as a gateway between protection relays, SCADA, and building or process controllers.
• Programmable automation: Built-in logic and scripting enable custom control sequences, event-driven actions, and local automation that reduce dependence on continuous operator intervention.
• High-resolution event and data logging: Time‑stamped sequence-of-events recording and continuous data logging provide forensic-quality records for diagnostics, commissioning, and compliance.
• Secure remote access and communications: Modern encryption, secure protocols, and support for VPN-compatible topologies help protect control-plane access and telemetry while enabling remote operations and maintenance.
• Cloud and third-party gateway compatibility: Designed to integrate with cloud services and third-party device gateways (for example HVAC and building gateways), RTAC can feed operational telemetry to remote dashboards and mobile apps for centralized monitoring.

Operational advantages

• Reduced downtime: Local automation and alarm handling accelerate fault response and allow automatic corrective actions when communications to central SCADA are interrupted.
• Improved situational awareness: Consolidated data streams, real-time monitoring, and sequence-of-events detail give operators clearer visibility into system health and transient events.
• Flexible integration: The RTAC’s protocol bridging simplifies integration of legacy devices and modern IEC-compliant equipment without major retrofit costs.
• Scalability: Modular deployment supports small remote sites through complex substations and allows phased expansion as operational needs grow.

Who should consider it

1. Electric utilities and independent system operators seeking resilient substation automation and reliable SCADA interfacing.
2. Industrial facility operators needing deterministic local control, event recording, and protocol translation between legacy devices and modern supervisory systems.
3. Integrators and OEMs implementing multi-vendor solutions that require a secure, configurable gateway for remote monitoring and cloud-enabled analytics.

Implementation notes

• Engineering and commissioning: Optimal results require careful configuration of communication channels, logic routines, and time synchronization; professional commissioning accelerates deployment and ensures interoperability.
• Cybersecurity: Follow industry best practices for key management, access control, and network segmentation; leverage the RTAC’s secure communication features and integrate with site VPNs and cloud security controls.
• Cloud/mobile access: For building systems, HVAC monitoring, or remote asset dashboards, pair RTAC deployments with compatible cloud gateways or services and mobile apps to extend monitoring to on-call staff and field technicians.

AcSELerator RTAC delivers the core functions needed for modern protection, control, and automation: robust protocol support, programmable local intelligence, detailed event recording, and secure remote connectivity. It is a practical choice for organizations that require dependable data consolidation and automation at the edge, with the flexibility to integrate legacy equipment and cloud-based monitoring solutions.
