UK-based test and measurement firm Pickering Interfaces has recently introduced a new series of programmable resistor modules for PXI and PXIe platforms, capable of handling up to 2 A and 200 V. This new range includes PXI model 40-254 and PXIe model 42-254, which are part of the company’s medium-to-high-power resistor modules lineup. These modules are compact and designed for applications that require one or two resistance channels, with each channel capable of handling up to 15 W of power.
Designed to simulate resistive sensors and variable resistors in systems during testing of devices like electronic controllers, the programmable resistors in the 40/42-254 family offer various resistance ranges and resolution capabilities. Ranging from 0.125 Ω to 8 Ω resolution and 1 Ω to 395 kΩ range, these modules can simulate short or open circuit conditions that may occur in a system due to faulty wiring or sensors. This flexibility makes them ideal for applications in automotive, as well as functional testing and verification of low-to-medium power products such as power supplies, chargers, batteries, solar panels, and DC-DC converters.
Paul Bovingdon, Simulation Product Manager at Pickering, highlighted the benefits of these programmable resistor modules, emphasizing their fault insertion functionality and flexibility compared to hard-wired, fixed-function load resistors commonly used in test fixtures or custom load boards. By enabling multiple devices to be simulated through software-controlled resistance adjustments, the PXI/PXIe programmable resistor modules offer a more versatile solution for testing various devices. This adaptability allows for validation against potential fault conditions and brings similar functionality to the modular PXI platform.
Pickering’s investment in simulation technology is evident in the development of these new PXI and PXIe programmable resistor modules, which cater to the evolving needs of the automotive industry and other sectors requiring simulation capabilities. With a focus on medium-to-high-power resistor modules, the company continues to expand its range to meet the demands of testing electronic controllers and other devices. The compact design of the 40/42-254 family makes them suitable for applications with limited space and the need for precise resistance simulation.
In conclusion, Pickering Interfaces’ latest programmable resistor modules for PXI and PXIe platforms offer a versatile and flexible solution for simulating resistive sensors and variable resistors in testing environments. With a wide range of resistance options and resolution capabilities, these modules cater to various applications in industries like automotive, power supply testing, and more. By incorporating fault insertion functionality and dynamic resistance adjustment, these modules provide an efficient and effective alternative to traditional load resistors, enhancing the testing capabilities of the PXI platform. Overall, these new modules represent Pickering’s commitment to innovation and meeting the evolving needs of the test and measurement industry.
