5.1.2 Auxiliary supply voltage input
The auxiliary voltage of the protection relay is connected to terminals X100:1-2. At
DC supply, the positive lead is connected to terminal X100:1. The permitted auxiliary
voltage range (AC/DC or DC) is marked on the top of the LHMI of the protection
relay.

5.1.3 Binary inputs
The binary inputs can be used, for example, to generate a blocking signal, to unlatch
output contacts, to trigger the disturbance recorder or for remote control of protection
relay settings.
Terminals X120:1-4 are binary input terminals. In the protection relay variant B, there
are additional binary inputs X120:5-6 included. Optional BIO-module BIO0006 for
slot X130 can be included at the time of order.
Binary inputs of slot X120 are available with configurations A and B.
