National Instruments 780587-25 PXI Multiplexer Switch Module 

National Instruments part number 780587-25 is an identifying part number for the PXIe-2525, a PXI Multiplexer Switch Module with 150 V Maximum Switching Voltage, Maximum Switching Current of 2 A, and Maximum Switching Power of 60 W, 62.5 VA. The NI 780587-25 is a high-performance, 64-channel multiplexer switch module from National Instruments. It efficiently routes signals within an automated test system and features a 2-wire topology with various configuration schemes, including 16 bank 4x1, octal 8x1, quad 16x1, dual 32x1, and 64x1. This versatility allows this device to meet diverse testing needs. Additionally, it includes a built-in relay counting mechanism for relay monitoring. 

The module supports a maximum switching voltage of up to 150 volts for both channel-to-channel and channel-to-ground specifications. The NI 780587-25 Multiplexer Switch Module features CH-COM DC isolation resistance, typically valued at 1 Giga-ohm at 25 degrees Celsius. It has an RF measurement bandwidth of up to 10 MHz. The module's built-in relays are electromechanical and non-latching, with field-replaceable relays made of palladium-ruthenium covered in gold. This PXI express device requires 20 W at 12 V and 3.4 W at 3.3 V. It operates using the NI-SWITCH driver software. 

This module is rated for Measurement Category I. It is designed to carry signal voltages up to 150 V. It can withstand impulse voltages up to 800 V. It should not be used for connections or measurements within Categories II, III, or IV. It should not be connected to MAINS supply circuits, such as 115 VAC or 230 VAC wall outlets. The electromechanical, non-latching relays in the 780587-25 multiplexer switch module have palladium-ruthenium contacts that are coated in gold. It features a 160-position male DIN 41612 connector on the front panel. The power requirements for this PXI Express module are 20 W at 12 V and 3.4 W at 3.3 V.
