Analog input or frequency input
Process volume, given volume, control volume, triple display
PID regulator, positive and negative action. Manual/automatic two-way switch
If resistance, even, line break, control volume, process volume analog output, can choose 0%、100% or upper limit amplitude, lower amplitude
Track zero point and full range of input signal to mark
Smart sound and light alarm, double timer or calculator
Evolution and small-signal can be removed
Feedback signal of valve position can be freely chose
External given value input
Can separately set control range of upper limit, lower limit output.
PID parameters can be self- adjusted or P parameters independently adjusted
Eight groups of setting value and P、I、D parameters store and adjust
Four switching capacity control output
Two or three analog output: 0～10mA or 4～20mA
