Simpler vision systems

Simplified vision systems with power over Ethernet frame grabbers

National Instruments has announced the NI PCIe-8236 and NI PCIe-8237R two-port GigE Vision frame grabbers featuring PoE technology. The PCIe-8237R features LabVIEW FPGA-enabled I/O, including isolated digital inputs and outputs, as well as bidirectional TTL lines for implementing custom counters, PWM signals and quadrature encoder inputs. It also offers advanced triggering and synchronisation options, such as a low-jitter, low-latency FPGA-based network trigger as well as RTSI synchronisation bus support.

Both frame grabbers are fully compliant with isolation specifications in the PoE standard to provide additional safety for the vision system and its operators. They can also interface with the latest low-cost PoE cameras on the market as well as non-PoE GigE Vision cameras with cable lengths up to 100 m.

“With these new frame grabbers, you can power a camera, perform triggering and acquire images from a single Ethernet cable,” said James Smith, Director of Industrial Embedded Marketing at National Instruments. “Engineers are constantly being challenged to do more with less, so this is a huge advantage for anyone building a vision system.”
