Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted. All voltages are specified in DC, ACpk, or a combination unless otherwise specified. Caution The protection provided by the NI 2738 can be impaired if it is used in a manner not described in this document. Input Characteristics Maximum switching voltage .................................................................... Channel-to-channel 100 V Channel-to-ground .................................................................... 100 V, CAT O Note This module is rated for Measurement Category I. It is intended to carry signal voltages no greater than 70 Vrms, 100 Vpk, or 100 VDC. 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 VAC or 230 VAC. Measurement Categories CAT I and CAT O (Other) are equivalent and are for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. This category is for measurement of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special hardware, limited-energy parts of hardware, circuits powered by regulated low-voltage sources, and electronics. Caution When hazardous voltages (>42.4 Vpk/60 VDC) are present on any channel, safety low-voltage (≤42.4 Vpk/60 VDC) cannot be connected to any other channel. ............................................................................ Maximum switching power 60 W, 62.5 VA Caution The switching power is limited by the maximum switching current, the maximum voltage, and must not exceed 60 W, 62.5 VA. Maximum current Switching ....................................................................2 A (per channel) Carry .................................................................... 2 A (per channel) Minimum switching load ............................................................................ 20 mV/1 mA Note Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module’s rated voltage. Without additional protection, these transients can interfere with module operation and impact relay life. 2 | ni.com | NI PXIe-2738 Specifications For more information about transient suppression, visit ni.com/info and enter the Info Code relayflyback. DC ............................................................................ isolation resistance 1 GΩ (typical at 25º C) (channel-to-COM) DC path resistance Initial .................................................................... <1.3 Ω End-of-life .................................................................... ≥2.3 Ω Path resistance is a combination of relay contact resistance and trace resistance. Measure path resistance by combining resistance of the high and low signal paths from one row to one column. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above ≥2.3 Ω. Thermal ............................................................................
