National Instruments 780587-75 PXI Multiplexer Switch Module. 

The part number 780587-75 from National Instruments is the identifying part number for the PXIe-2575 PXI Multiplexer Switch Module. This module has been built with different configurable methods that enables the module to connect and switch signals, such as the 1-wire 196 × 1 multiplexer, 2-wire 95 × 1 multiplexer and the 2-wire 98 × 1 multiplexer. This module supports maximum switching voltage of 100 V channel to channel and 100 V, CAT channel to ground. It has maximum switching power of 60 W per channel, with a DC isolation resistance of >1 GΩ, typical at 25 °C between channel and COM terminals and a maximum current of 1 A. 

The 780587-75 PXI Multiplexer Switch Module has a relay operate time of 1 ms, typical 3.4 ms, maximum with a expected mechanical relay life of 1 × 10^8 cycles and electrical life of 2.5 × 10^6 cycles in 10 VDC, 100 mA DC resistive, 1 × 10^6 cycles in 10 VDC, 1 ADC resistive and 5 × 10^5 cycles in 30 VDC, 1 ADC resistive. The input source trigger signals of the 780587-75 module can be routed to trigger lines 0 through 7 with a maximum pulse width of 150 ns. These trigger lines in a module are used for system synchronization and system coordination when connected with other modules while the destination output trigger signals can be routed to trigger lines 0 through 7 with a pulse width of 1 μs to 62 μs. To power the module 6 W at 5 V and 2.5 W at 3.3 V.

The PXI module is designed as a single-slot 3U (3 unit) module compatible with PXI (PCI extensions for Instrumentation) or cPCI (CompactPCI) systems. Its dimensions are 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and weighs 231 g (8.1 oz). To operate this module it is recommended by the manufacturer to use it in an environment with an ambient temperature between 0   to 55 degrees Celsius and can also be stored in an environment with a temperature of -20 to 70 degrees Celsius. The relative humidity rating for storage is 5% to 95%, non-condensing while for operating it has relative humidity of 10% to 90%, noncondensing. With a Pollution degree level of 2 this module is suitable for environments with low to moderate levels of contamination.
