Pickering Interfaces designs and manufactures modular signal switching and simulation for use in electronic test and verification. Specified in test systems installed throughout the world, Pickering Interfaces’ products have a reputation for providing excellent reliability and value. A global company, Pickering serves all electronics industries including, automotive, aerospace & defense, energy, industrial, communications, medical and semiconductor.

In 2018, Pickering Interfaces introduced a new family of 110-strong family of 2.5W, 5W and 10W programmable resistor modules targeting ECUs and fuel level sensing. The model 40-251/2/3 resistor modules family are 110 high-accuracy programmable resistor modules with 2.5W, 5W or 10W power handling capability at 100V or as limited by power. Models 40-251/2/3 target applications that require accurate medium-power programmable resistance such as a programmable load for the testing of Electronic Control Units (ECUs) and fuel level sensing. These ECUs are commonly used in the demanding, hi-reliability, automotive, military and aerospace sectors.

As the models offer such a huge choice of resistance channel counts, ranges and setting resolutions, they address a wide variety of medium-power electronic Test & Measurement applications, delivering test engineers exactly what they need rather than forcing them to accept a compromise.

Available in modular PXI format for flexible and scalable system integration, the model 40-251/2/3 resistor modules are compatible with a wide range of chassis, including PXI, PXIe Hybrid, cPCI and Pickering USB/LXI chassis, for flexible functional test system integration. With between 1 and 8 resistance channels per module, resistance settings from 1Ω to 22MΩ and resolutions from 0.125Ω to 2Ω, the most suitable module may be selected for any specific application.

Resistor channels are simply programmed by the use of resistance calls to the software driver. Each channel can be set as short or open circuit to simulate a wiring or sensor fault, and simplified DMM module verification is provided via an optional calibration cable.

Pickering Interfaces stands behind all of its manufactured products with a standard three-year warranty and guaranteed long-term product support.
