- [FX32EV] Electronic Expansion Valve Controller(PWM Type)
- - Superheat Control by PID
- Various Types of Refrigerants Compatible
- PWM(Pulse Width Modulation) and Valve Open Ratio Control
- Remote Operation
- Analog Signal Output(4-20mA)
- Communication via RS485 MODBUS
With the advanced PID algorithm, FX32EV controls electronic expansion valves and superheat precisely.
Various Types of Refrigerants Compatible
R22, R134a, R404a, R407c, R410a, R717, R23 are compatible and more refrigerants will be available soon.
PWM(Pulse Width Modulation) and Valve Open Ratio Control
It is possible to control from 0.0 to 100.0 % by 0.1% of PWM(pulse width modulation). Duty cycle can be set from 1sec
to 99.9sec by 10msec.
Remote Operation
Analog Signal Output(4-20mA)
FX32EV retransmits the analog signal(4-20mA) to other devices or equipments.
Communication via RS485 MODBUS
It is versatile. Communication via RS485 provides many options to the users(remote control, remote display, data
manipulation, and etc.)
