Power supply for sensors

24V terminal on the input terminal block can supply current to the external equipments. If this output is used as the
power supply for the input of own unit, the remaining can be used as power supply for the sensors. The current (I)
allowed using as the power supply for sensors can be calculated by the following formula.
I = 430 mA – (5 mA* × NI + 5mA × NO)
NI: number of input in active at the same time
NO: number of output in active at the same time
*: Replace 10mA instead of 5mA for input bit 0, 2, 4, 6 and 8.
