•Total current consumption of Output block
(Current consumption of one output x Output number) x Output block number =
(20 mA x 2 points) x 6 blocks = 240 mA
•Current consumption of the load connected to the manifold block for low wattage load.
(Total current consumption of connected load) + (Current consumption of one valve x station number) =
(62 mA + 62 mA) + (42 mA x 7stns.) = (124 mA) + (294 mA) = 418 mA
Total current consumption = 240 mA + 418 mA = 658 mA ≒ 0.7 A
Maximum supply current for SI unit (EX250-SDN1) = 2 A
0.7 A ≦ 2 A
