NI PCI-6528



NI PXI-6528, PCI-6528, and PXI-6529 devices are industrial channel-to-channel isolated digital I/O interfaces for PCI and PXI.

You can use the optically isolated inputs of NI 6528 and PXI-6529 devices to read the status of sensors, actuators, and logic devices.

NI 6528 devices have 24 solid-state relay outputs to switch external devices with input currents up to 150 mA.

With high-current drive and isolation, NI 6528 and PXI-6529 devices are ideal for a variety of applications from automotive design, industrial factory automation, and
machine control to aerospace, laboratory research, and biomedical applications.

Industrial digital I/O devices are designed to incorporate the latest hardware technologies for applications requiring ease of use,

high reliability, and performance. NI 6528 and PXI-6529 devices are jumper-free and take advantage of NI-DAQmx measurement services
software to speed up application development with features such as the DAQ Assistant, automatic code generation, and high-performance multithreaded streaming technology
