Servo amplifier PSAP4B
Electronic proportional servo circuit of electric actuator uses SMT technology, with the advantages of small volume and high reliability. It controls 4-20mA current signal and on or off the action of actuator according to the deviation by the comparison with the current position of the actuator signal so that it can make Balance of mechanism position and input signal.
PSAP4B inputs 4-20mA in the implementation of actuator, and also provides 4-20mA position signal to the system.

PSAP4B can easily adjust the actuator starting position and stroke ,role switching and set that when the input signal fault occurs, the mechanism is in fully open/fully closed or maintain state.


Working principle
The position signal conversion circuit will reflect the change of the 1000 Ω resistance signal of actuator position and transfers to 4-20mA. The control input and position signal will be sent to the bias amplifier for comparison at the same time. And the comparison results can control the solid state switch on/off so that it can control the open and close actuator. Adjustment of the sensitivity on the basis of control requirements, you can change the tracking precision and eliminate Oscillations due to mechanical inertia.


Additional stroke (2WE) and additional torque(2DE) switch
Additional stroke (2WE) and additional torque (2DE) switches are a set of additional switches, which can output 2 passive contact signal (5A 220VAC) when the actuator is in the appropriate position or torque.


Single/double valve position (POT/POT2)
Output 1 group (POT) or 2 groups (POT2) with the same valve position value of 0 to 1000 resistance signal as a servo amplifier valve position feedback signal or transfer to the instrument as a valve position display.

HR
It is installed within the actuator to maintain a certain temperature so that it can avoid frost or damages in the low temperature (-20).

PSMF
When it is not necessary to match the built-in servo amplifier, it only needs to output 4-20mA valve position signal.

Application
It is suitable for 90°rotary valve (i.e. ball valve, butterfly valve ) (Special voltage PSMS)and throttle switch and Boiler field.
