The PR120/K fitted with four relays having contacts named K51/p1, K51/p2, K51/p3 and K51/p4 which can signal different situations selectable
by the user from among those given the standard list, whereas customizations can programmed selecting "custom" the menu and
setting the signal required with PDA, SD-Testbus PR010/T.
