Build cleaner low-voltage control projects with purpose-built boards for power distribution, load switching and isolated field-signal inputs. Use each board independently or combine them into one documented controller system.
Convert one 18–30V DC supply into the regulated rails commonly needed by controller projects.
Available now · $37.50
Control compatible 12V and 24V DC loads from low-voltage controller outputs.
Available now · $19.95
Safely interface 9–30V DC field signals with 3.3V or 5V controller inputs.
Available now · $19.95 · Limited first-production stock
The boards solve different parts of a controller installation. Ratings shown here are summaries; review the applicable product documentation before wiring or applying power.
| Board | Use it when you need to | Electrical interface | Documentation |
|---|---|---|---|
| PWR INTF Power and interface |
Power a controller and distribute low-voltage DC from one 18–30V supply. | Regulated 12V, 5V and 3.3V rails plus fused input-voltage distribution. | Published |
| OUT-4 Protected outputs |
Switch compatible 12V or 24V DC loads from controller GPIO. | Four protected low-side MOSFET outputs. Follow the published channel and total-current limits. | Published |
| IN-4 Isolated inputs |
Monitor 12V or 24V field signals using 3.3V or 5V controller GPIO. | Four polarity-independent 9–30V DC inputs with optocoupler isolation and active-high logic outputs. | Quick Start, owner's manual, specification sheet and mechanical information published |
Use PWR INTF to distribute power, OUT-4 to switch external DC loads and IN-4 to monitor field signals. Every board can also be used by itself. KI Maker publishes the wiring, electrical limits and operating information needed to evaluate each board before it is connected to a controller.
Low-voltage DC electronics only.
These boards are intended for maker projects, prototypes, test fixtures and low-voltage control applications. They are not certified safety barriers and are not intended for AC mains, medical, life-safety, emergency-stop or fail-safe applications.
