Message:WRT-422 PI control can measure temperature through either internally-mounted temperature sensor or external temperature sensor. The switch of internally-mounted or external sensor can be realized through a switching device. The control can figure out the position of actuator by proportional-integral control function so as to keep the target temperature at set point. Features (1) 2-loop PI controller; (2) 1 output for 0...10VDC or 0(4)...20mA; (3) 1 input for 0...5VDC, 0...10VDC or 0(4)...20mA sensor; (4) Optional connection for extermal NTC temperaturesensor; (5) 3 Relays controlled binary outputs, option for floating outside, 3A/250VAC One loop specially is used control to fan or pump; (6) Password protected programmable user and control parameters (7) Blue backlight. Specifications Power Voltage: AC24V 50/60Hz Power consumption: 2VA Setting range: 0~140℃ or 0-198F Resolution: 0.5K Sensing organ: NTC thermistor, 10k (at 25℃) Ambient temp. range: -10~50℃ Humidity: 95%max Protect rank:: IP30 Material of shell: ABS +PC Dimensions (H×W×D): 86×86×37mm
