UK-based test and measurement firm Pickering Interfaces has launched a new range of PXI and PXIe programmable resistor modules, its first that can handle up to 2 A and 200 V.

Part of the company’s expanding range of medium-to-high-power resistor modules, the PXI (model 40-254) and PXIe (model 42-254) products follow on from the company’s 2.5 W (model 40-251), 5 W (model 40-252), and 10 W (model 40-253). Their compact design is aimed at applications requiring one or two resistance channels, with up to 15 W of power handling capability per channel.

Programmable resistors are designed to simulate resistive sensors and variable resistors in systems when testing devices such as electronic controllers. The 40/42-254 family is available in a variety of resistance ranges and resolution capabilities from 0.125 Ω to 8 Ω resolution and from 1 Ω to 395 kΩ range. Each channel can simulate short or open circuit conditions that can be experienced in a system caused by faulty wiring or sensors.

“Part of Pickering’s ongoing investment in simulation, these PXI/PXIe programmable resistor modules are ideal for automotive applications, as well as functional test and verification of low-to-medium power products such as power supplies, chargers, batteries, solar panels and DC-DC converters,” said Paul Bovingdon, Simulation Product Manager at Pickering. “The modules’ built-in fault insertion functionality is ideal for validating against potential fault conditions. These programmable modules offer a more flexible alternative to the hard-wired, fixed-function load resistors often found in test fixtures or custom load boards, bringing similar functionality to the modular PXI platform, but enabling multiple devices to be simulated by dynamically changing the amount of resistance through software.”
