Digital/ Fiber Optical Input Card (GN4070)

The Binary Marker HV card is a dedicated input option for GEN DAQ products.

It enables to record up to 32 binary input channels (marker channels) as well as 8 digital event signals that are optically isolated with up to 1 MS/s per channel.

Although general purpose, this board is specifically suited for the high power/high voltage market. A fiber-optic isolated output is provided to present an ARM signal that can be used to drive an external instrument like the HBM BE3200 high-definition test sequencer or any other timing device. The ARM output is active when a continuous recording is active, or when the acquisition card is waiting for a trigger (armed) in the triggered sweep acquisition mode.

In addition, 9 binary input channels can be assigned under software control to provide 3 channels of timer/counter functionality. Each channel can have its own function.

The timer/counter functionality includes:

  • General purpose up/down counter
  • Frequency/RPM counter
  • Quadrature/ position measurements

The timer/counter functionality uses up to 3 event bits per channel. These event bits also keep their original functionality. E.g. you can use a quadrature encoder and at the same time look at the quadrature signals separately.

HBM Perception software provides integrated display and control of the event channels that are recorded in parallel with the analog channels. A full range of features is available for each channel separately to make the best use of the event channels.

Settings include name, units, invert, and storage on/off.

In addition each event channel can be used as a trigger condition, a qualifier or an alarm. Each of these conditions can be set to either positive/negative or high/ low active. This combination of features gives you the capability to create complete "bit patterns" to be used as trigger or qualifier.

Note: The timer/counter channels cannot be used for triggering or alarm.
