1.1 The actuator is designed with a servo system (no additional servo amplifier is required), and it only needs to connect to DC4~20mA (or DC1~5V) signal and AC220V single-phase power supply to work. Built-in terminal block, wiring is extremely simple and convenient.
1.2 The key component of the actuator, the controller, adopts advanced hybrid integrated circuits, is sealed and cast with resin, and has a box-like shape, small size and high reliability.
1.3 The feedback detection of driving quantity adopts high-performance conductive plastic potentiometer, and the resolution is less than 0.4%.
1.4 With self-diagnosis function, when a fault occurs, the indicator light on the controller will immediately send out an indication signal.
1.5 The state selector switch can be used to set the off signal (the valve core is in the fully open, fully closed or self-locking state).
1.6 It can be set by the state selector switch (forward and reverse action).
1.7 The input signal can be set as (DC4～20mA or DC1～5V) with the state selection switch.
1.8 It is easy to adjust the working zero point (start point) and stroke (end point).
1.9 When the power is suddenly cut off, it can ensure that the valve core is self-locking.
1.10 Adopt synchronous belt drive to effectively reduce noise.
1.11 Time-delay protection function, state self-locking can be implemented at rated load, protection can be started immediately when a fault occurs, and time-delay protection can be canceled by reverse operation.
