The drainage and irrigation station centralized controller circuit consists of the knife switch Q, fuse FU, start buttons S1, S3, stop buttons S2, S4, intermediate relay KA, AC contactor KM, thermal relay KR, fluorescent starter Κ, resistors RI, R2 and light HL, and the circuit is shown in the chart. S1, R1, S2, and HL form the control and instruction circuit which is installed in the control room, and each irrigation station has a signal line connected to the circuit. RI and R2 select the 300 ~ 1000Ω, 2 ~ 3W wire wound variable resistors. S1 and S3 use 380V, 5A press-pressure making buttons; S2 and S4 use 380V, 5A press-pressure moving off buttons.
