Options

◎ standard connection type (type B) causes circuit-switched on / off valves with outputing active contacts signal to show a fully open or completely closed state of the valve.
◎ Passive contact type (type S) causes the circuit switched on / off valves with outputing passive signal contacts to show a completely open or completely closed state of the valve.
◎ With type of position signal (type K) it makes the valves on / off by circuit switching with outputing current signal corresponding to the valve on / off angle.
◎ Opening grade signal type (R type) controls the open angle valves by circuit switching, meanwhile output potentiometer signals outputs corresponding to the open angle valve.
◎ type of intelligent modulation (type A) realizes intelligent regulation and control by receiving a standard 4-20mA.DC, 0-10V.DC or 1-5V.DC output signal from the computer or the industrial instrument, as well as the 4-20 mA outputs. DC standard feedback signal.
