IO Guide — DI/DO/AI/AO
This Guide consists of four most common I/O types with interactive examples:
- DI — Digital Input with NO contact
- DO — Digital Output driving a pump
- AI — Analog Input with NTC10k divider
- AO — Analog Output (0–10 V) to a valve

Digital Input (DI) — DI+ / DI− with NO contact
Logic value:
0
Animated arm closes the contact; wires and nodes glow when closed.
Digital Output (DO) — DO+/DO− driving a pump
STOPPED
DO: 0
Analog Input (AI) — AI+ at divider node, AI− to GND
Resistance: 10.000 kΩ
Analog Output (AO) — AO+/AO− to Valve (0–10 V)
Valve Position: 0%
