6Ai6Ro — Sense & Switch

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.
