National Instruments 777802-01 Isolated Digital I/O

Often known as the PXI-6527, the National Instruments 777802-01 is a flexible 48-bit parallel isolated digital I/O interface made for PXI or CompactPCI chassis and PCI bus computers. This cutting-edge gadget has 24 optocoupler inputs and 24 solid-state relay outputs that together provide 48 channels of independent digital data capture. Its design allows it to switch currents up to 120 mA and sense digital levels up to 28 VDC. Furthermore, digital filtering features are used to remove errors from the input lines, guaranteeing precise data collection. For the purpose of alerting users to changes in the data, all input lines are capable of producing interrupts on rising or falling edges.

The 777802-01 performs well in low-voltage isolation and switching applications, making it suitable for use in both industrial and laboratory settings. The solid-state relay outputs can be used to switch external devices, even ones that need higher input currents, while the optically-isolated digital input lines are intended to read the status of external digital circuitry at both TTL and non-TTL levels. Users may effectively adjust digital logic levels thanks to this functionality as well. Because of its separated design, this device decouples computer noise and hard ground conditions from external signals, improving the stability and dependability of your operations.

The 777802-01 comes with the NI-DAQ driver software. A wide range of application development environments can use the extensive library of functions provided by NI-DAQ. This makes the device an outstanding option for a variety of data collecting purposes by enabling customers to fully utilize all of its functions.

The 777802-01 offers remarkable flexibility and capability with its 24 optically-isolated digital input channels, each featuring a ground reference that is isolated from other channels, and 24 solid-state relay output channels, each featuring two terminals that are isolated from other channels. Solid-state relays with typically open form A further increase their usefulness in a range of applications.
