The Part Number 778572-75 refers to a PXI Switch categorized under PXI Switches with the model name PXI-2575. This device is a PXI Multiplexer Switch Module that utilizes Electromechanical Relays to facilitate connectivity. It offers various topologies including 1-wire 196 x 1, 2-wire 95 x 1, and 2-wire 98 x 1 Multiplexer configurations, providing flexibility for different wiring needs.
The module features socketed relays, which means that the relays can be replaced if necessary, extending the device’s lifespan. These relays boast an electrical life of approximately 105 operations, ensuring reliability and durability. The switch’s bandwidth reaches up to 20 MHz, with a maximum switching power of 60 W, 62.5 VA (DC to 60 Hz) per channel, suitable for a variety of applications.
A notable feature of this module is its relay count tracking, which helps monitor relay usage and anticipate maintenance needs. Connectivity is facilitated through a 200 POS LFH Matrix 50 I/O connector, providing ample interfacing options. However, it is not recommended for 2-wire resistance measurements, due to its design and operational characteristics.
The typical relay operating time is 1 ms, with a maximum of 3.4 ms, ensuring swift response times for applications. Relay contacts are made from silver with gold covering, offering excellent conductivity and resistance to corrosion. The device can handle up to 140 cycles per second, making it capable of high-speed operations.
Compatibility with software is broad, including NI-SWITCH, NI-DAQmx, Measurement Studio for Visual C++, NI Switch Executive, LabWindows/CVI, and LabVIEW, ensuring that the module can be integrated into a wide range of
