Control & power
- Control type
- 0–10 / 2–10 V control · 4–20 mA control
- Power supply
- 24 V AC/DC
Use a 2–10 V control output and separate 24 V supply. The documented 4–20 mA arrangement requires a 500-ohm resistor; it is not a direct relay input.
A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.
Technical specifications
Selection & installation notes
- Actuator must match the valve and coupling. A simple on/off relay does not provide proportional control.
