6ADi4Ro2AVo2AIo
Sense, Switch & Drive6 multifunction inputs, 4 relays, 2× 0-10V and 2× 4-20mA outputs — the full-loop controller for modulating analog equipment.
Why 6ADi4Ro2AVo2AIo
Full Mixed I/O
The only RTU controller in the range with analog outputs — combine digital, voltage, and current signals in one compact DIN-rail unit.
Precise Control Signals
2 × 0-10V outputs for modulating valves and dampers. 2 × 4-20mA outputs for variable-speed drives and actuators requiring current loop control.
Advanced Automation
Up to 16 built-in automation rules — twice the capacity of other models. Handle complex multi-condition logic without an external controller.

Use Cases
HVAC with Valve Control
Read temperature and pressure sensors on multifunction inputs. Modulate chilled water valves and air dampers via 0-10V outputs. Switch fans and pumps via relays.
Pump Speed Control
Drive variable-frequency drives (VFDs) via 4-20mA outputs for precise pump speed control. Monitor flow and pressure via analog inputs. Override via relay for on/off operation.
Complex Automation Setups
Use up to 16 automation rules to handle multi-stage control sequences — combining digital events, analog thresholds, relay switching, and analog output modulation in one unit.
