■Wiring

○Power supply wiring
Power supply line inside the SI unit has individual power supplies for solenoid valve actuation (SV power
supply) and for control parts and input block (SW power supply). Supply 24 VDC for each of them.
: In case of single power supply, pay attention to the range of each supply voltage.
Power for sensor is supplied to sensor connected with input block. Select sensor concerning voltage drop
up to maximum 1 V inside the unit at this moment.
If sensor requires 24 V, it is necessary to lower power supply voltage for sensor slightly or secure power
supply for sensor separately without going through SI unit so that sensor input voltage can be 24 V with
actual loading (allowable voltage of power supply: 19.2 to 28.8 V).
