11 Appendix 11.6 Appendix F: Current Consumption of an EH2/EH3 Series PLC/an Extension Module Users can calculate the maximum current consumed by an EH2/EH3 system by means of the data in the table below. Current supply and current consumption of a PLC (+24VDC) #1: Internal current supplied Internal maximum current consumed + Internal maximum current consumed by the IO-BUS #2: External current supplied Maximum current consumed by the external DIO + Maximum current consumed by the external digital input/output module + Maximum current consumed by the external special input/output module #3: The external maximum current consumed is estimated on the basis of a worst condition.
It is suggested that users (AIO module) should calculate the maximum current consumed according to the actual arrangement. Current supply and current consumption of a digital input/output module (+24VDC) Current consumption of a special input/output module (+24VDC) A special input/output module must be supplied with +24VDC power.
