PXI-6527 | NI Isolated Digital I/O Module

48-Bit Isolated Digital I/O• 24 optically isolated digital inputs (0-28 VDC)• 24 isolated, solid-state relay digital outputs (0-60 VDC, 0-30 Vrms)• Switch up to 120 mA• Digital filtering on inputs• Messaging (change notification)• NI-DAQ driver simplifies configuration and measurementsNI 6527 devices are 48-bit, parallel, isolated DIO interfaces for PCI and PXI. They have 24 optically isolated digital inputs and 24 solidstate relay outputs. NI 6527 devices can sense digital levels up to 28 VDC and switch currents up to 120 mA. The channel-to-channel isolated inputs and outputs protect your system, reduce noise, and break ground loopsNI 6527 devices can generate a message when one or more userselected input lines changes, either from low to high, high to low, or both. Once notified of a change, NI-DAQ can read the status of other input lines, set outputs, or perform some other programmed operation. Using this feature, you can monitor lines without polling, thus using your CPU more efficiently.
