Typical application for the YAV904X8 are Isolated measurements (no reference to GND) performed by DMMs (2 or 4 wire). The board contains four groups of eight relays each; these can be configured either as a 32 position scanner or a matrix.

The board is powered and controlled by a four pin connector containing the 24Vdc input to power the board and all relays.
The same connector contains also the two Can bus lines to control the board. All relay outputs are isolated from the power supply.

The module features a logic address setting by means of a set of dip switches. A maximum of 64x YAV904X8 boards are possible in one test system.

A virtual software panel, that can be used with National Instruments LabView® or TestStand®, is available to simply integrate the instrument into the test sequence.
