11 Appendix Calculating the maximum current consumed by a system The power module optionally purchased is DVPPS02. (It supplies 2A current.) Example: 28SV2 + 16SP + 04AD-S + 04TC-S + EN01-SL Maximum current consumed: Internal 170 + 65 + 30 + 30 + 60 = 355 (mA) External 3.8A + 5A + 83mA + 83mA = 9A > 2A Not pass Conclusion: The 2A current supplied by DVPPS02 is sufficient for the PLC and the special modules. If the external I/O terminals are connected to loads, it is suggested that users should purchase an extra power module.
