The digital input/output option card is inserted in the upper
option card slot in the back of the VAMP 59 protection relay
and the module is fasted to VAMP 59 with two screws.
Figure 8-2 VAMP 59 with digital input/output option card.
Digital inputs of VAMP59 –relays can operate in three different
voltage areas. It is also possible to select whether ac or dc –
voltage is used. Digital input threshold of VAMP 59-relays is
selected in the ordering code when the relay(s) are being
ordered. The threshold voltage selection is done with jumpers
at the factory. In case that the DI/DO –option card is ordered at
the same time as the relay, the threshold of the option card is
also modified at the factory according the ordering code of the
relay.
Sometimes option cards might be ordered afterwards and in
those cases they are not modified at the factory. In cases like
this the cards has to be modified during the commissioning. See
the pictures presented below.
When 110 or 220 V ac voltage is used to activate the digital
Inputs, the AC mode should be selected as shown in the
screenshot below:
