|3/4/5 Port Solenoid Valves

Is there polarity for connecting electrical wiring to the DC type of the VP300/500/700 series?

When the lead wires of the valve are identified by the colors red and black, the red color is the polar (positive) and the black color is the non-polar (negative). Please connect + (positive) lead wire to terminal 1 and - (negative) lead wire to terminal 2 in the DIN terminal type or any other terminal type without lead wires.
In addition to the non-polar type such as VP342-5DU1-01A products, we recommend you connect the lead wire + (positive) to terminal 1 and the lead wire - (negative) to terminal 2 in case of changing to the polar type.
