PXIe-2727 Specifications

This document lists specifications for the PXIe-2727. All specifications are subject to change without notice.

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 Typical unless otherwise noted.

Conditions

Specifications are valid at 23 °C unless otherwise noted.

All voltages are specified in DC, ACpk, or a combination unless otherwise specified.

Input Characteristics

Number of channels

9

Maximum voltage

Channel-to-channel

60 VDC, 30 VACrms, 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.

Channel-to-ground

60 VDC, 30 VACrms, CAT I

Maximum current

0.3 A (per channel)

Maximum power

0.25 W (per channel)

Resistor accuracy

0.5%

TCR

100 ppm

Resolution

0.25 Ω steps

Range

0.25 Ω to 16,383 Ω (per channel)

Typical channel accuracy

Channel set between 20 Ω and 40 Ω

<10.0%

Channel set between 40 Ω and 120 Ω

<5.0%

Channel set between 120 Ω and 400 Ω

<2.0%

Channel set between 400 Ω and 16,000 Ω

<1.0%

Channel accuracy is a function of the overall resistor accuracy, plus relay and trace path resistance, plus any effects of temperature.

Typical minimum resistance

2 Ω

Typical DC offset resistance (per channel)

Initial

<2 Ω

End-of-life

≥3 Ω

Channel resistance is a combination of relay contact resistance, trace resistance, and resistor value. Contact resistance typically remains low for the life of a relay. At the end of relay life, the offset resistance may rapidly rise above 3 Ω.

The following figures show the expected resistance error and the expected resistance.

Dynamic Characteristics

Simultaneous drive limit

161 relays

Relay operate/release time

250 μs

Note Certain applications may require additional time for proper settling. Refer to the NI Switches Help for information about including additional settling time.
Typical relay life

Low power load (<50 mW)

1 × 108 cycles

Full power load (<250 mW)

1 × 106 cycles

Note Reed relays are highly susceptible to damage caused by switching capacitive and inductive loads. Capacitive loads can cause high inrush currents, whereas 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, visit ni.com/r/relaylifetime. For information about inductive loads, visit ni.com/r/relayflyback.
Note The relays used in the PXIe-2727 are field replaceable. Refer to the NI Switches Help for information about replacing a failed relay.

Trigger Characteristics

Input trigger

Sources

PXI trigger lines <0...7>

Minimum pulse width

150 ns

Note The PXIe-2727 can recognize trigger pulse widths that are less than 150 ns by disabling digital filtering. For information about disabling digital filtering, refer to the NI Switches Help.

Physical Characteristics

Relay type

Reed

Note NI advises against installing reed relay modules directly adjacent to an embedded controller with a magnetic hard drive because of the sensitivity of reed relays and the possibility of interference.
