Input Section Specifications
Note
The current consumption is for Bit Slave Unit communications cur-
rent when all inputs are OFF, i.e., it does not include input device
current consumption. The communications power supply is also
used for the I/O power supply for sensors. Be sure to consider the
sensor current consumption and the number of sensors connected
in addition to the communications power. The power supply current
consumption is expressed by the following formula.
Communications power supply current consumption = Bit Slave
Unit communications current consu (Bit Slave Unit input
current
×
number of inputs used) + (sensor current consumption
×
number of sensors used)
