PCI-922116-bit PCI DAQ board with encoder reading
- Manufacturer
PCI-9221 is a multifunction data acquisition board for the PCI bus, suited to test benches and automatic cells where analog measurement lives alongside the reading of an axis position.
Sampling reaches 250 kSps with DC input coupling. In differential encoder mode the board calls for an additional 24 V supply on the dedicated pins of connector CON1, a condition to allow for in the field wiring.
