Output Section Specifications
Note The current consumption is for Bit Slave Unit communications cur-
rent when all outputs are OFF, i.e., it does not include the output de-
vice load current consumption. The communications power supply
is also used for the I/O power supply for actuators. Be sure to con-
sider the actuator load current consumption and the number of sen-
sors 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 (actual load current
×
number of actuators used)
