○EX250-SAS9
•
Current consumption in the Output block
(Current consumption of one output x Output points) x Output block number =
(20 mA x 2 points) x 1 blocks = 40 mA
•
Current consumption of the load connected to the sensor, load connected to the Output block and
manifold valve.
(Total current consumption of sensors) + (Total current consumption of connected loads) + (Current consumption
of one valve x station number) = (10 mA) + (40 mA) + (20.8 mA x 1 stn.) = 70.8 mA
Total current consumption
= 40 mA + 70.8 mA =
110.8 mA
Maximum supply current for SI unit (EX250-SAS9)
=
120 mA
Result
110.8 mA
≦
120 mA
