GXGS814 double impulse feedwater intellectual regulator.
System principle
Two columns digit display measuring and given value, two LED columns display control value and procedure parameter.
Manual--- automatic changeover function.
Anti-integral saturation and amplitude limiting PID adjustment, realization of system self-adjustment.
"Increase-decrease" function can be chosen.
Up and low limit alarm relays output
Output for control: DC 4-20mA, 0-10mA
24V DC output
Trace input: realize manual-auto changeover without disturbance.
Precision: 0.5
Communication interface: RS-485
Power supply: AC220V
Size: 80*160*95mm (vertical)
160*80*95mm (horizontal)
Signal merge coefficient:
F=IN1+C3*IN2
C3 is vapor flux coefficient: -1.000--+1.000 adjustable
When f=0, the signal will be cancelled.
The output is given out by PID calculation after comparing the merged signal f and given value.
