FIG 0.1 — INTERKEY BRAIN · INDUSTRIAL CONTROL, REIMAGINED
The complete industrial PLC.
One cabinet. Everything included.
Describe your machine in plain language. Brain generates the control system, validates every change, guides commissioning step-by-step, runs safely on five-tier authorization, and recovers from failures without losing data.
Air-gapped • EU AI Act-aligned • Five-tier safety authorization • Full audit trail
ONE CABINET. EVERYTHING INCLUDED.
No SCADA. No HMI vendors. No integration. Just Brain.
Open the box. Power it on. Everything works. Controller hardware, I/O modules, power distribution, 14" status display, NVIDIA Jetson AI co-processor, and the full software stack — all in one cabinet. Four interfaces for every user: HMI Tablet for operators, Admin Dashboard with 55+ pages for engineers, 14" Status Panel for at-a-glance monitoring, and a Mobile Setup App for commissioning. Application-agnostic — runs freeze dryers, HVAC, packaging machines, bottling lines, ovens, conveyors, breweries, and smart buildings.

BRAIN AI
Tell Brain what you need. Watch it build.
Describe your machine in plain language — heaters, sensors, PID targets, safety limits. Brain's AI agent streams its tool calls in real time: reads your hardware, writes ST code, builds HMI, configures alarms, runs a simulation. Complete control system in minutes, not months.
From natural language to running PLC
Describe “build a freeze dryer with 4 heaters, PID control at 60°C, operator dashboard, alarm if >80°C” — Brain streams 7 tool calls in real time: reads your hardware, writes ST code, builds HMI, configures alarms, starts simulation, verifies, returns a summary. Done in 2 minutes, not 2 months.
Downtime if the cloud goes down
Brain’s AI is optional. The PLC engine, hardware drivers, protocols, and alarm processing all run independently. Network failure, AI service outage, backend crash — the cabinet keeps your machine running. Hardware watchdog on every I/O board (2s timeout). Circuit breaker on AI service. Graceful degradation.
Forever license. No maintenance contracts.
Brain Core €2,500. Brain Pro €5,000. One-time purchase. Lifetime firmware updates. Optional subscriptions for cloud features — but you never need them. Compare to Siemens TIA Portal’s €3,000+/year maintenance, Rockwell FactoryTalk’s per-seat licenses, and Beckhoff’s per-CPU charges.
ARCHITECTURE
The real stack.
Engineers buy from diagrams. Here's what actually runs inside Brain.
STM32 Firmware
Deterministic C on Cortex-M4. 2 s hardware watchdog.
RS-485 Bus
Modbus RTU. Up to 32 I/O modules per segment.
Brain OS
Drivers, tag system, historian, protocols, security.
PLC Engine
IEC 61131-3 scan cycle. Runs independently of AI.
AI Agent
100+ tools. 5-tier safety. Multi-provider.
MCP Server
Exposes Brain as Model Context Protocol endpoints.
External Clients
Claude, GPT, custom agents, SCADA, ERP, cloud.
Data flow: sensor → bus → OS → control → intelligence → protocol → consumer.
THE BRAIN STACK
Not three products.
One vertically integrated platform.
Every layer designed by Interkey. Every layer working together.
From the STM32 firmware on an I/O board to the AI agent in your browser — one system, one supplier.
Brain Agents
Watchdog / Responder / Optimizer. Five agents, one closed loop.
Brain Vision
Self-learning visual and acoustic monitoring on Jetson.
Brain AI
100+ tools, plugin SDK, 5-tier safety, multi-provider, MCP server.
Brain Studio
HMI Builder, PLC IDE, Process Designer, batch control.
Brain OS
Tag system, PLC engine, protocols, historian, security, fleet management.
Brain I/O
STM32F412 boards on RS-485 Modbus. WPRTD, WPIO, WPPWR/WPPWS, WPPSU.
Interkey Sense
PoE industrial cameras, microphones, vibration sensors.
From freeze dryers to breweries. One brain runs them all.
END-TO-END PROCESS
From description to production.
BRAIN VISION
Your machines learn to watch themselves.
Self-learning cameras and microphones on NVIDIA Jetson. Up to 20 cameras and 10 microphones per cabinet. Water levels, color shifts, gauge readings, vibration anomalies — Brain Vision learns what normal looks like in 6 hours, then guards your process autonomously. Zero programming. Zero training data.
WHAT OUR PARTNERS SAY
From our
launch customer.
Brain is changing our complete approach to machine programming. We have less cost and so much more to offer to the customer!
BRAIN STUDIO
Design operator screens in minutes.
Drag and drop from 17 widgets. Bind to live I/O with one click. Publish directly to the operator tablet — no export, no deploy pipeline, no waiting. PLC programming in all 5 IEC 61131-3 paradigms. Recipe management and ISA-88 batch control built in.
BUSINESS MODEL
One system. One supplier.
No integration.
Brain replaces your SCADA software, HMI panels, engineering workstations, and separate PLC — with one cabinet. One purchase, everything works. No integration projects. No annual license renewals. No finger-pointing between five different vendors when something breaks.
No SCADA License
Brain includes the complete monitoring and control stack. No per-seat SCADA licenses, no annual renewals, no surprise costs at scale.
No Integration
Controller, I/O, HMI, AI, and vision — designed as one system from day one. Boots to operational. Speaks Modbus, MQTT, OPC UA, and SparkPlug B natively.
No Vendor Lock-in
Open protocols, local AI processing, and full data sovereignty. Your data stays in your building. Switch or scale on your terms.
Air-gapped. Sovereign. No data leaves your building.
SCALE
One cabinet today. An entire factory tomorrow.
Deploy Brain across your production floor — every cabinet inherits proven control logic, adapts to its specific machine, and connects to the unified monitoring platform. Modbus, MQTT, OPC UA, SparkPlug B, and cloud bridge — all built in.
