PXI-2532B Specifications

These specifications apply to the PXI-2532B.

All specifications are subject to change without notice.

Notice The protection provided by the PXI-2532B can be impaired if it is used in a manner not described in this document.

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical specifications describe the performance met by a majority of models.
  • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Warranted unless otherwise noted.

Conditions

Specifications are valid at 23 °C unless otherwise noted.

Input

Caution

This module is rated for Measurement Category I and 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 VAC or 230 VAC.

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.
Table 2. Maximum Switching Voltage, Current, and Power
Maximum switching voltage, channel-to-channel 100 V
Maximum switching voltage, channel-to-ground 100 V, CAT I
Maximum current 0.5 A (switching or carry, per channel)
Maximum switching power 10 W (per channel)
Note The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 10 W.
Table 3. DC Path Resistance
Initial <1 Ω, warranted
End-of-life ≥2 Ω
Open channel >1 × 109
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 2 Ω. Load ratings apply to relays used within the specification before the end of relay life.

Dynamic

Table 8. Dynamic
Simultaneous drive limit 64 relays
Relay operate time 0.25 ms
Release time 0.25 ms
Relay life (no load), mechanical 1 × 109 cycles, typical
Note Relay operate time may be longer; certain applications may require additional time for proper settling.
Note Optional series protection resistance, available for the terminal blocks, increases the expected relay life at higher voltages. This series protection resistance shields the reed relays from the effects of cable and load capacitance. For more information, refer to the NI-SWITCH User Manual.
Note Reed relays are highly susceptible to damage caused by switching capacitive and inductive loads. Capacitive loads can cause high inrush currents while inductive loads can cause high flyback voltages. The addition of appropriate resistive protection can greatly improve contact lifetime. For more information about adding protection circuitry to a capacitive load, refer to the NI-SWITCH User Manual. For information about inductive loads, visit ni.com/r/relayflyback.
Note The relays used in the PXI-2532B are field replaceable.
