Electronic control unit uses the most advanced hybrid integrated circuits, it is designed box shape, including complete protection, field control or remote control, and sealed with a resin casting. AC drive motor with reversible motor, the feedback amount detecting conductive plastic potentiometer with high performance, high reliability economic type products with 1/250 resolution capabilities. Straight trip all-electronic actuators adjust themselves almost have various actions demand opening signal conversion function and function and manual functions. Features: 1, the actuator servo system design (no need to reprovision servo amplifier), simply access the DC4 ~ 20mA (or DC1 ~ 5V) signal and AC220V single-phase power supply to work. Equipped terminals, wiring is very simple and convenient. 2, the implementation of the key components - controller, using the most advanced hybrid integrated circuits, sealed with a resin cast of box-like shape, small size and high reliability. 3. The amount of feedback detection drive high-performance conductive plastic potentiometer, resolution <0.4%. 4, with a self-diagnostic function, when a failure occurs, the indicator on the controller will issue an instruction signal immediately. 5, with the state selection switch can be set off signal (spool is fully open, fully closed or locked state). 6, with the state selection switch can be set (positive and negative action). 7, with the state selection switch can be set to the input signal (DC4 ~ 20mA or DC1 ~ 5V). 8, adjustments zero (starting point) and stroke (end) easy. 9, when a sudden power failure, to ensure the self-locking spool. 10, synchronous belt drive, effectively reducing the noise. 11, delay protection, the rated load, can carry out the state of self-locking, when a failure occurs, can start immediate protection, and reverse run canceled delay protection. Technical parameters: Power supply voltage AC220 ± 10%, 50HZ. Power consumption (at rated load) Specifications A-type actuator 50VA; specifications B-type actuator 150VA; specifications C type actuator 220VA DC4 ~ 20mA input signal or the output signal of DC4 ~ 20mA (load resistance 500Ω or less) or DC1 ~ 5V control Accuracy basic error: ± 1%; Hysteresis ≤1%; dead zone ≤1% working stroke adjustment range "zero" ± 25%; "stroke" by 20% to 100% protection IP55 flameproof grade Exd II BT4 Overload protection Specifications A, B actuators can be optional, standard C-series actuators must be equipped with
