APEX WAVES NI PXI-2523 26-Channel DPDT Relay Module

Product Information

The PXI-2523 is a 26-channel DPDT (Double-Pole Double-Throw) relay module. It is a general-purpose relay module that provides switching capabilities for various applications. The module is non-latching, meaning it does not require continuous power to maintain its relay positions. The specifications listed in this document outline the performance and characteristics of the PXI-2523 module.

Specifications

Topology : 26-channel DPDT, non-latching
Maximum switching voltage:
- Channel-to-channel: 100 V
- Channel-to-ground: 100 V, CAT I (Measurement Category I)
Switching Power Limit: 60 W, 62.5 VA
DC Path Resistance: Initial – [No value provided in the text]

Note: The PXI-2523 module is designed for use with signal voltages not exceeding 100 V. It is not suitable for connection to higher voltage circuits or mains supply circuits (115 or 230 VAC). It is important to refer to the safety and electromagnetic compatibility documents for proper usage and precautions.

This document lists specifications for the NI PXI-2523 general-purpose relay module. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications.

Caution: The protection provided by the NI PXI-2523 can be impaired if it is used in a manner not described in this document.

Topology ………………………………………………….. 26-channel DPDT, non-latching

Refer to the NI Switches Help for detailed topology information.

About These Specifications

Specifications characterize the warranted performance of the instrument under the stated operating conditions.
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: Refer to the Read Me First: Safety and Electromagnetic Compatibility document for important safety and electromagnetic compatibility information. To obtain a copy of this document online, visit ni.com/manuals, and search for the document title. To ensure the specified EMC performance, operate this product only with shielded cables and accessories.

Input Characteristics

Maximum switching voltage

Channel-to-channel …………………………….. 100 V
Channel-to-ground. …………………………….. 100 V, CAT I

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 or 230 VAC. Refer to the Read Me First: Safety and Electromagnetic Compatibility document for more information on measurement categories. 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. The switching power is limited by the maximum switching current, the maximum voltage, and must not exceed 60 W, 62.5 VA.

Maximum switching power (per channel) ……………………………………………..60 W, 62.5 VA (DC to 60 Hz)
Maximum current (switching or carry, per channel ) ………………….2 A Simultaneous channels at maximum
current (≤55 °C) …………………………………………26
Minimum switching conditions ……………………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.

Info Code relayflyback.

DC path resistance

Initial …………………………………………………<0.5 Ω
End-of-life …………………………………………. ≥1.0 Ω

DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rises rapidly above 1 Ω. Load ratings apply to relays used within the specification before the end of relay life.

Thermal EMF (typical at 23 °C ) …………………..12 μV
Bandwidth (-3 dB, 50 Ω termination, typical at 23 °C)
- 1-wire ……………………………………………….. ≤70 MHz
- 2-wire ……………………………………………….. ≤35 MHz
Crosstalk (typical at 23 °C, 50 Ω termination)

- 100 kHz. …………………………………….. ≤-45 dB

Isolation (typical at 23 °C, 50 Ω termination)

Open channel

10 kHz. ………………………………………. ≥75 dB
100 kHz ……………………………………… ≥55 dB

Dynamic Characteristics

Relay operate time

Typical ……………………………………………… 1 ms
Maximum ………………………………………….. 3.4 ms
Simultaneous drive limit …………………………….. 26 relays

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

Expected relay life

UMechanical ………………………………………… 1 × 108 cycles

Electrical (resistive)

30 V, 1 A ……………………………………. 5 × 105 cycles
30 V, 2 A. …………………………………… 1 × 105 cycles
