Figure 8.5-1 VAMP 50 with arc option card.
The arc information can be transmitted and/or received
through digital input and output channels BIO. The output
signal is 48 V dc when active. The input signal has to be 18 …
48 V dc to be activated.
The GND must be connected together between the GND of the
connected devices.
The binary output of the arc option card may be activated by
one or both of the connected arc sensors, or by the binary input.
The connection between the inputs and the output is selectable
via the output matrix of the device. The binary output can be
connected to an arc binary input of another VAMP protection
relay or arc protection system.

NOTE! When this option card is installed, the parameter "I/O" has value "VOM
6DI1DO". Please check the ordering code in chapter 12.
NOTE! If the slot X6 is already occupied with the two channel arc sensor card
(chapter 8.5), this option is not available.
The digital input/output option enables four more digital inputs
and one digital output (trip contact). These inputs are useful in
applications where the contact signals are not potential free.
For example trip circuit supervision is such application. The
digital output uses terminal slots X6:1 and X6:2. DI3-DI4 are
using the common in terminal slot X6:4. DI5-DI6 are using the
common in terminal slot X6:7.
