FIG 0.1 — INTERKEY BRAIN · INDUSTRIAL CONTROL, REIMAGINED

The complete industrial PLC.
One cabinet. Everything included.

Describe your machine in plain language. Brain builds the control program, operator screens, alarms, and PID loops — autonomously. From freeze dryers to bottling lines, from HVAC systems to smart buildings.

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.

Interkey Brain — Industrial PLC Cabinet

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.

2 min

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.

Zero

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.

€2,500

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.

END-TO-END PROCESS

From description to production.

01

Describe

Tell Brain AI about your machine in plain language. "I have a freeze dryer with 4 heaters and need PID control targeting 60°C."

02

Generate

Brain AI creates the PLC program, HMI operator screens, alarm configurations, and PID loops — all from your description.

03

Simulate

Test your entire control system in simulation mode before a single wire carries current. Verify logic, tune PID, and stress-test alarms.

04

Commission

Auto-discover I/O modules on the bus. The Mobile Setup App guides you through wiring verification and first power-on, step by step.

05

Operate

Four interfaces go live: operators use the HMI Tablet, engineers use the Admin Dashboard, the Status Panel shows at-a-glance health, and recipes execute on schedule.

06

Optimize

AI Watchdog scans health every 5 minutes. Responder triggers real-time alarm rules. Optimizer analyzes efficiency daily and tunes your process continuously.

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.

Freeze dryers, breweries, bottling lines, and industrial ovens — all controlled from one cabinet with recipe management and batch control built in.

02

Building Automation

HVAC systems, smart buildings, and energy management. Brain monitors every zone, optimizes energy use, and adapts to occupancy patterns autonomously.

03

Manufacturing

Packaging machines, conveyors, CNC coolant loops, and assembly lines. Brain Vision watches for anomalies while Brain AI optimizes throughput.

04

Pharma & Defense

Air-gapped operation with local AI. No telemetry, no cloud dependency, full data sovereignty. Built for classified facilities and GMP-regulated environments.

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.

OUR MISSION

Making industrial automation accessible to everyone.

Industrial machines deserve better than decades-old control systems that require specialized engineers, expensive licenses, and months of integration. We believe every machine builder, every factory operator, and every process engineer should be able to describe what they need — and get a running control system in return.

Interkey Brain is our answer: a vertically integrated PLC where hardware, software, and AI work as one. No vendor lock-in, no license fees, no cloud dependency. One cabinet that boots to operational and speaks every industrial protocol. Built for the engineers who build the world.
