Caution The protection provided by the PXI-2515 can be impaired if it is used in a manner not described in this document.

About These Specifications

Maximum and minimum specifications are warranted not to exceed these values within certain operating conditions and include the effects of temperature and uncertainty unless otherwise noted.

Typical specifications are unwarranted values that are representative of a majority (90%) of units within certain operating conditions and include the effects of temperature and uncertainty unless otherwise noted.

Characteristic specifications are unwarranted values that are representative of an average unit operating at room temperature.

All specifications are characteristic unless otherwise specified.

Nominal specifications are unwarranted values that are relevant to the use of the product and convey the expected performance of the product.

Notice Do not connect to Res0. Res0 is reserved for future use.
Notice Use only the NI SHC68-C68-D5 cable to connect the supported NI high-speed DIO device to the module. The cable translates the pinout of the supported NI high-speed DIO device to the HSDIO connector on the module so that the pinout of the DUT connector on the module matches that of the supported NI high-speed DIO device.
Note ctrl0, ctrl2, and ctrl3 do not route through relays, but rather pass through from the left connector to the right connector. These channels cannot be connected to the analog bus channels, busa and busb.

Input Characteristics

All input characteristics are DC, ACpk, or a combination unless otherwise specified.

Maximum switching voltage

Channel-to-ground

30 V, CAT I[1]1 Measurement Categories CAT I and CAT O (Other) are equivalent. These test and measurement circuits are not intended for direct connection to the MAINs building installations of Measurement Categories CAT II, CAT III, or CAT IV.

Caution When hazardous voltages (>42.4 Vpk/60 VDC) are present on any relay terminal, safety low-voltage (<42.4 Vpk/60 VDC) cannot be connected to any other relay terminal.
Caution The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 3 W.

Maximum switching power (per channel)

3 W

Maximum switching current

0.25 A

Maximum carry current

0.3 A

Typical skew

Channel-to-channel

<130 ps (across all data channels)

Note DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rapidly rises above the end of life value. Load ratings apply to relays used within the specification before the end of relay life.

Estimating Reed Relay Life

Complete the following steps to estimate relay lifetimes using the nomograph:
  1. Determine the peak voltage experienced across the relay while switching and mark this value on the Volts line.
  2. Determine the sum of the DUT, cable, and instrumentation capacitances and mark this value on the Load Capacitance line.
  3. Draw a straight line between both values.
    The intersection points of this line and the No Protection and 50 Ω Protection axes are the corresponding estimated relay lifetimes in cycles.

Estimating Reed Relay Life Example

The reed relay module is connected to a DMM through 1 meter of cable. The DMM and cable capacitances are 100 pF and 30 pF respectively. The maximum voltage switched across the relay is 50 V. Determine the estimated number of relay cycles with and without protection resistance.

Solution

The total load capacitance is the sum of the cable and DMM capacitance, which is 130 pF. Draw a line between the 50 V point on the Volts axis and 130 pF on the Load Capacitance axis.

The line drawn intersects the Cycles axes at approximately 500,000 on the No Protection axis and about 25,000,000 on the 50 Ω Protection axis, as shown in the following figure. This series resistance should be placed as close as possible to the relay for maximum effect.
