Input Characteristics

Maximum switching voltage
Channel-to-channel	150 V DC, 150 V AC
Channel-to-ground	150 V DC, 150 V AC, CAT II^[1]¹ Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.

Caution This module is rated for Measurement Category II and intended to carry signal voltages no greater than 150 V AC/150 V DC. This module features 1,400 Vrms isolation between input signals and the backplane as verified by a dielectric withstand test, one-minute maximum. Do not use this module for connection to signals or for measurements within Categories III or IV. Do not connect to MAINs supply circuits (for example, wall outlets) greater than 150 V DC; do not connect to MAINs circuits of 208 V AC (US) or 230 V AC (Europe).

Caution When hazardous voltages (>42.4 Vpk/60 V DC) are present on any relay terminal, safety low-voltage (≤42.4 Vpk/60 V DC) cannot be connected to any other relay terminal.

Caution The switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 30 W at 150 V DC, 150 W at 30 V DC, or 150 V AC, 5 A.

Maximum switching power (per channel)

750 VA

DC
30 V	150 W
150 V	30 W

Maximum current (switching or carry, per channel)

5 A

Simultaneous channels at maximum current (≤55 °C)

Caution Switching inductive loads (for example, motors and solenoids) can produce high-voltage transients in excess of the rated voltage of the module. Without additional protection, these transients can interfere with module operation and impact relay life. For more information about transient suppression, visit ni.com/info and enter the Info Code induct.

DC path resistance
Initial	<100 mΩ
End-of-life	≥250 mΩ

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

Minimum switch load

10 mA, 5 V DC

Dynamic Characteristics

Relay operate time

10.4 ms (maximum)

Note Certain applications may require additional time for proper settling. For information about including additional settling time, refer to the NI Switches Help at ni.com/manuals.

Expected relay life
Mechanical	2 × 10⁷ cycles
Electrical (full load)	1 × 10⁵ cycles

Note The relays used in the PXI-2564 are field replaceable. Refer to the NI Switches Help at ni.com/manuals for information about replacing a failed relay.

Minimum pulse width^[2]² The PXI-2564 recognizes trigger pulse widths less than 150 ns if digital filtering is disabled. Refer to the NI Switches Help for information about disabling digital filtering.	150 ns

Output trigger
Destinations	PXI trigger lines <0...7>
Default pulse width	2 µs, typical
