2.1.4.2. Supply voltage of the power components
The 24V power supply in the plant automation is carried out through the X13 connector (24V_In). After this is done the power supply to power controller leds and automatic low voltage 24V.
Protecting drivers power diodes LEDs are made by the fuse F1. To determine the value of the fuse F1 has to add the consumption of all drivers for the LED diodes. For example, if we have 4 active drivers with LED rated 1A, the maximum current is 4 amps, so you have to put a fuse from 4 to 5 amps.
 "Current value of F1")
It has a power output connector on the X14 (24V_Out) for the supply voltage of automatic low voltage (motors, sensors, electro-valves etc.). To protect the supply line of a short circuit is provided the fuse F2. The F2 fuse value depends on the consumption of automation that is controlled by X14. For example if it controls a solenoid valve that consumes 0.5A 1A fuse is sufficient. If you control a shutter motor 24V 100W, 4A consumption is and has to put a 5A fuse.
\ =\ \frac{P(W)}{V(V)}=\ \frac{100}{24}\ =\ 4,16\ A\ \equiv \ 5A "Current value F2")
