6Ai6Ro
Sense & Switch6 multifunction inputs, 6 relays — the universal automation controller with 0-10V, 4-20mA, and NTC support.
Why 6Ai6Ro
Flexible Inputs on Every Port
Every input port independently configurable as digital, 0-10V analog, 4-20mA current loop, or NTC temperature sensor — no rewiring required when requirements change.
Powerful Direct Switching
6 high-quality Omron relays rated 16A at 230V — directly control heating elements, contactors, pumps, and other heavy loads.
Standalone Operation
Built-in rule engine runs automation logic locally. No Modbus master required — continues operating even if the gateway goes offline.

Use Cases
HVAC Room Control
Read NTC temperature sensors and room state via multifunction inputs. Switch heating, cooling, and ventilation relays based on local automation rules — no cloud dependency.
Sensor Monitoring + Relay Automation
Mix digital inputs, 0-10V sensors, and 4-20mA transmitters on the same unit. Trigger relay outputs based on sensor thresholds with the built-in rule engine.
Building Management
Deploy across multiple zones in a building. Each 6Ai6Ro operates standalone, reporting to a Wolf Gateway or central Modbus master via RS-485.

Setting the Modbus Address with the Front-Panel Buttons
Every controller leaves the factory on address 1, so a bus with several new units has nothing to tell them apart. The four front-panel buttons set the Modbus address, baud rate and serial format on site — no master, no laptop, no software.
Two details worth knowing before you start: the value being edited is shown in binary on the six yellow relay LEDs — weights 1 · 2 · 4 · 8 · 16 · 32, add the lit ones — and the buttons reach addresses 1 to 62. Higher addresses are set over Modbus. The full button and LED reference is in the Product Manual above.
The same procedure applies to the 6Oi6Ro and the 6ADi4Ro2AVo2AIo.
