(3) Example of 5VDC internal current consumption and 24VDC current
calculation
(a) Example of 5VDC internal current consumption calculation
If the total 5VDC internal current consumption exceeds the maximum rated
output current 2.0A, mount a new bus refreshing module (ST1PSD). Attach
the bus refreshing module onto the base module for extension bus
refreshing
module (ST1B- 4P2-R-SET).
Total current consumption = 2.165(A)
1: Bus refreshing module (for powering head module)
Calculate the total 5VDC internal current consumption using the maximum
I/O point setting sheet given in Appendix 2 and 3. (Refer to Section 5.1, Section 7.1
and Section 7.2 for the current values of 5VDC internal current consumption.)
