Wiring diagram
CONTROL CIRCUIT
Ordinary switch type (A type)
The valve can be opened or closed through the switch circuit, and a set of activeposition models indicating that the valve is fully open and fully closed are output.
Passive contact type（B type)
Realize valve opening or closing operation through switch circuit, and output a setof passive position models indicating that the valve is fully open and fully closed
Opening signal type（C type)
Open or close the valve through the switch circuit, and output a resistance signalcorresponding to the opening position
With position transmitter (D type)
Realize valve opening or closing operation through switch circuit,and outputcurrent signal corresponding tovalve opening and closing angle at the same time.
lntelligent adjustment type(E type)
Control the opening and closing angle of the valve through the standard signalinput by an extenal computer or indus trial instrument, and synchronously outputthe correspond ing standard signal
DC switch type(F type)
By switching the positive and negative poles of the external DC power supply, thevalve can be“opened”and“closed”,and a set of passive contact signalsin dicating that the’valve is fully open or ciosed can be output
Three-phase switch type(G type)
The valve is opened or closed through the switch circuit, and a set of active positionsignals indicating the valve is fully open and fully closed is output.
Three-phase passive contact type(H type)
Realize valve opening or closing operation through switch circuit,and output a setof passive position signals indicating that the valve is fully open and fully closed.
Note: The dashed line in the control circuit is the internal circuit of the electric device.The parts outside the dashed line areonly for reference when the user is wiring.
