Total
1: Rated input current (4 input points) of the ST1X4-DE1 + load current of the external devices (4 sensors)
connected to the ST1X4-DE1
24VDC current = 0.004
2: Load current of the external devices (16 lamps) connected to the ST1Y16-TE2
24VDC current = 0.21
3: Current flowing in the relay coil of the ST1Y2-R2
24VDC current = 0.035(A)
4: 24VDC current of the ST1DA2-V = 0.2(A)

4 + 0.15 4 = 0.616(A)
16 = 3.36(A)
I = 0.616 5 + 3.36 5 + 0.035 = 19.915(A)
If power is supplied to I/O modules, the total 24VDC current is greater than the
maximum rated current 8.0A. Therefore, it is required to add the power feeding
modules (or bus refreshing modules).
I = 0.065 4 = 0.260 (A)
If power is supplied to intelligent function modules, the total 24VDC current is less than
the maximum rated current 3.0A. Therefore, it is not required to add the power feeding
modules (or bus refreshing modules).
