Description
The product with the part number 781985-22 is a PXI-2722 model, categorized under PXI Switches. It features a 5 Channel, 16-Bit configuration, designed as a Programmable Resistor Module. This module is capable of handling a maximum voltage of 60 VDC, 30 VACrms, CAT I (channel-to-channel and channel-to-ground), with each channel supporting a maximum current of 0.3 A and a maximum power of 0.25 W.
The module’s Temperature Coefficient of Resistance (TCR) is specified at 100 ppm, ensuring minimal resistance changes with temperature. Its steps resolution is remarkably fine at 0.25 Ω, allowing for precise adjustments. Each channel offers a wide range from 0.25 Ω to 16,320 Ω, accommodating a broad spectrum of applications.
The typical channel accuracy is maintained below 10.0% for resistances between 20 Ω to 40 Ω, and below 5.0% for resistances from 40 Ω to 120 Ω, ensuring reliable performance. The module’s design allows for a simultaneous drive limit of 89 relays, demonstrating its capability to handle multiple operations concurrently.
Furthermore, the relay life is rated at 1 × 108 cycles under low power load conditions (<50 mW), signifying its durability and reliability for long-term usage. This technical specification underscores the PXI-2722’s design and functionality, tailored for versatile and demanding applications in programmable resistance modules.
