ZXQ2004 positioner

ZXQ2004 positioner

Product description:

This locator accept from the host instrument DC4-20mA / 1-5V DC Regulatory signals and lower electric actuator potentiometer ' Three-wire ' Signal output ' open ' and ' turn off ' Signal, the valve opening degree of control and regulation is widely used in the single-phase AC motors and actuators equipped with (such as angle valve actuators with linear electric actuator). It can be very convenient and RC , UNIC ,3410 ,3610 , NA , HQ , PSQ Consisting of different modulating valve actuator (throttle, baffle) drive means

Control accuracy: 0.1% -3.0% (adjustable);

Can be accessed by electric actuator feedback signal: potentiometer 500Ω-10KΩ;

You can receive an external control signal (DC): 4-20mA, other former factory customized input signal;

When the actuator can be set forward and reverse operation mode and the input signal is interrupted 'interrupt' mode -OPEN (open), STOP (stop), SHUT (closed);

You can set whether to allow electronic braking;

SCR output: AC, 600V, 25A;

Actuator position output signal: low drift output 4-20mADC correspond fully closed to fully open the actuator, the input signal is completely isolated (optical isolation);

Ambient temperature: 0-70 ℃ (can be set), humidity: 35-85%;

Over-temperature protection;

ZXQ2004 Dimensions: 74mm (bottom surface length) x57mm (bottom wide) x45mm (H);

The actuators can correspond freely through the key input signal calibration operation section (generally calibrated to the electric actuator fully closed, fully open position);

Manual / automatic bumpless switching;

Actuator stall detection and control functions;

It can be set to allow to change the precision or retune time;

Password lock, to prevent misuse;

According to the input signal and the angular position of the actuator intelligent step away from the precise positioning adjustment;

With error code indicating the cause of failure;

Special requirements can be customized.
