1 NI PXI/PXIe-2575 Specifications196 1 Relay MultiplexerThis document lists Specifications for the NI PXI/PXIe-2575 (NI 2575) 196 1 multiplexer relay module. All Specifications are subject to change without notice. Visit for the most current 1-wire 196 1 multiplexer 2-wire 95 1 multiplexer 2-wire 98 1 multiplexerRefer to the NI Switches Help for detailed topology These SpecificationsSpecifications characterize the warranted performance of the instrument under the stated operating conditions. Typical Specifications are Specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 C. Typical Specifications are not warranted. All voltages are specified in DC, ACpk, or a combination unless otherwise specified. Clean devices and terminal blocks by brushing off light dust with a soft, nonmetallic brush. Remove other contaminants with a soft, lint-free, dampened cloth. Do not use detergent or chemical solvents.

2 The unit must be completely dry and free from contaminants before returning to to the Read Me First: Safety and Electromagnetic Compatibility document for important safety and electromagnetic compatibility information. To obtain a copy of this document online, visit , and search for the document ensure the specified EMC performance, operate this product only with shielded cables and protection provided by the NI 2575 can be impaired if it is used in a manner not described in this document. 2| |NI PXI/PXIe-2575 SpecificationsInput CharacteristicsMaximum switching voltageChannel-to-channel .. 100 VChannel-to-ground .. 100 V, CAT ICautionThis module is rated for Measurement Category I and is intended to carry signal voltages no greater than 100 V. This module can withstand up to 500 V impulse voltage. Do not use this module for connection to signals or for measurements within Categories II, III, or IV. Do not connect to MAINs supply circuits (for example, wall outlets) of 115 or 230 VAC.

Without additional protection, These transients can interfere with module operation and impact relay life. For more information About transient suppression, visit and enter the Info Code path resistanceInitial.

4 < 1 DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rapidly rises above 1 .
