The Problem
Your PLCs speak Modbus. Your protection relays speak DNP3. Your SCADA historian speaks OPC-UA. Your analytics platform speaks MQTT. Between them: custom scripts, protocol gateways, middleware stacks, and weeks of integration work that breaks with every firmware update.
70% of industrial digitisation projects fail — and the primary cause is data quality and integration complexity. There is no trusted data layer at the operational edge.
Why RelayQ Exists
Self-Contained
One binary. Under 3 MB. Zero external dependencies. No JVM, no container runtime, no cloud connection required. Deploys in air-gapped networks with no supply-chain risk.
Deterministic
Bounded memory. Bounded latency. Predictable behaviour under every failure condition. Built in Rust with zero garbage collection. Suitable for critical infrastructure.
Non-Intrusive
Deploys beside existing control systems as a read-only observer. Never modifies PLC logic. If RelayQ stops, your plant continues operating unchanged.
Trusted
Every data point carries provenance metadata: where it came from, when, at what quality. Ed25519-signed binary. Hardware-bound licensing. Full audit trail.
Where It Fits
Brownfield Digitisation
Connect decades-old PLCs to modern analytics without replacing hardware or modifying control logic. Deploy RelayQ today; structured data flows tomorrow.
Critical Infrastructure Monitoring
Substations, treatment plants, pipeline compressor stations — environments where deterministic behaviour and store-and-forward are not optional.
Multi-Site Fleet Operations
Water utilities, mining operations, distributed generation — dozens or hundreds of sites managed with consistent data quality from a single pane.
Cloud Integration Without Cloud Dependency
Bridge edge data to AWS, Azure, or GCP when connected. Continue operating with full local capability when disconnected. Never lose a data point.
