NI PXI-2503 PXI switch module

NI PXI-2503 PXI switch module

Specification parameters
Channel configuration: Supports 1-wire, 2-wire or 4-wire configuration, and can achieve 48×1 (1-wire), 24×1 (2-wire), 12×1 (4-wire) modes, paired with TB-2605 terminal block accessories; It can also be configured as a 4×6 (2-wire) matrix mode through the TB-2606 terminal block accessory.
Switching voltage: Capable of switching signals up to 60 VDC or 30 VRMS.
Thermal offset: For low-voltage measurements such as thermocouple signals, the relay has a very low thermal offset (less than 2μV) to ensure precise measurement.
Current handling capacity: At A voltage of 30 VDC, it can handle up to 1 A of current, making it suitable for automotive-grade voltage measurement.

Functional characteristics
Scanning list: Equipped with a 1024-step scanning list for convenient deterministic scanning operations.
Software programmability: Fully controlled by software programming, it can be configured and operated through the NI-SWITCH driver software. Combined with the help documentation, sample programs and soft front panel applications, interactive control of the switch is achieved.
Hardware-triggered synchronization: It is easy to achieve instrument synchronization through hardware triggering, and can work precisely in synchronization with other PXI devices, ensuring the accuracy and reliability of the system.

Application field
Semiconductor testing: In the semiconductor manufacturing process, it is used to test the signal routing between the equipment and the chip or circuit board under test, achieving rapid switching and measurement of multiple test points.
Power electronics testing: It can be used for performance testing of power electronic equipment, such as connecting different power supplies, loads or measuring instruments to the equipment under test to measure and analyze various electrical parameters.
Data acquisition: In the data acquisition system, multiple sensors or signal sources are connected to the data acquisition equipment. Through the switch switching of PXI-2503, the time-sharing acquisition and processing of different signals are achieved.
