z
In the above table, the residual capacity is calculated according to the most power-consuming model (for
example, MCT) of in each main/expansion unit by its I/O point number, under the maximum load condition (with
both DI and DO ON). The basic units for calculation are 7.5mA /PT for high/medium speed DI, 4.5mA/PT for low
speed DI (Ultra high speed DI does not use the 24VDC power in input circuit), 10mA/PT for high speed DO,
7.5mA/PT for medium speed DO, and 5mA for low speed DO and relay output. (excluding the SSR model).
z
See Sections 5.1 and 5.2 for the residual capacity of expansion power (-EPW-AC and -EPW-D24)
Warning
Either for the built-in power supply of the main/expansion unit or the expansion power supply for the expansion
unit, the total amount of current cannot exceed the value listed in the above table. Any violation will cause a
voltage drop by overloading the power supply, or intermittent powered with the supply in protection mode, either
of which will result in unexpected action of PLC and cause harm to people or damage to equipment.
5.3.2 Maximum Current Consumption of Expansion Module
Without its own power supply, expansion modules must be supported by the main/expansion unit, expansion power, or
external power supply (24VDC input circuit alone). The following table lists the maximum consumption current of each
expansion module.
