HL8102 PID Temperature Controller
The HL8102 series digital temperature controller is a microprocessor-based controller with digital LCD display.
The controller is used to control room temperature in industrial, commercial and residential environment via controlling electric modulating valve / damper with 0-10Vdc (4-20mA) signal or floating control.
The controller provided proportional plus integral (PI) control with modulating and floating control output.
