5.3 Residual Capacity of Main/Expansion Unit & Current Consumption of Expansion
Module
Besides its own circuits usage, the residual capacities of three sets of built-in power supply of main/expansion unit are
big enough for other expansion modules usage. In addition, the expansion power (FB
S
-EPOW) module can also provides
the power for expansion modules usage. As each model of the main/expansion unit has different residual capacity,
various models of expansion modules also consume different amounts of current. In practice, one has to consider the
match between the two to avoid overload in any of the three sets of output power. In the following, the worst case of the
available residual capacity in each main/expansion unit and the maximum power consumption of expansion modules are
described below spare.

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 (-EPOW and -EPOW-D)
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.
