Actuator
WRA-6320A AC220V±15%, 50/60Hz, on/off
Output torque: > 3.5N.m Angle of rotation: 90°
Protect rank: IP55/IP54 On/off time: 16S
Function ( 3-point or on/off type )
The actuator is controlled by a modulating on/off or 3-point control signal, using r eversible synchronous motor and gear speed reducer drive to fix and lock.
WRA-6320A on/off type
B lack wire is the control wire. Power on: valve open, power off: valve close
Brown wire is connected to the power wire.
Blue wire is connected to the com. Only can be used as on/off type.
