功能介绍 Function introduction

●控制方式 Control mode

1、开关型执行器：24V电源控制阀门开关，4～20mA信号反馈 Switch type actuator: 24V power supply control valve switch, 4~20mA signal feedback

2、调节型执行器：4～20mA输入信号控制开度，4～20mA信号反馈 Regulating actuator: 4~20mA input signal control opening, 4~20mA signal feedback

● 调节型作用方式：正作用(4mA信号时阀开，20mA信号时阀关)或反作用(4mA信号时阀关，20mA信号时阀开) Regulating action mode: positive action (valve open when 4mA signal, valve close when 20mA signal) or negative action (valve close when 4mA signal, valve open when 20mA signal)
