Communications power supply
current consumption *
65 mA max. for 24-VDC power supply voltage
80 mA max. for 14-VDC power supply voltage
45 mA max. for 24-VDC power supply voltage
65 mA max. for 14-VDC power supply voltage

* The current consumption is for Bit Slave Unit communications current 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 consumption + (Bit Slave
   Unit input current x number of inputs used) + (sensor current consumption x number of sensors used)

* The current consumption is for Bit Slave Unit communications current when all outputs are OFF, i.e., it does not include
   output device load current consumption. The communications power supply is also used for the I/O power supply for
   actuators. Be sure to consider the actuator load current consumption and the number of actuators 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 consumption + (Bit Slave
   Unit input current x number of inputs used) + (actuator load current x number of actuators used)
