Pickering offers a variety of PXI programmable resistor modules and PCI programmable resistor cards for use in medical, automotive and aerospace applications. We have developed over 160 PXI modules and 150 PCI cards. Our entire range uses real resistors; they do not use current loads or other electronic means to control the resistance value. Therefore they behave in exactly the same way as an actual resistor.
In their simplest form, our programmable resistors consist of a basic chain of resistance values switched in or out of circuit with reed relays, electro-mechanical relays or solid state switches. We also offer multi-channel programmable resistors with very fine value adjustment and high accuracy including programmable resistive bridges for strain gauge simulation.
Our PXI programmable resistor modules are ideal for medical, aerospace and automotive applications and feature:

Advantages of these Programmable Resistors include:
- They replace the need for real sensors
- No need to physically simulate sensor's environment
- Allow you to reuse between test applications and give you accuracy, speed, and repeatability.
The resistors have the additional capability of being set as open and short circuit to simulate faults in the sensor connections to the ECU. Specific versions of these modules have been developed to simulate Resistance Temperature Devices (RTD) (PXI 40-262 series and PCI 50-262 series) and strain gauges (PXI 40-265 series and PCI 50-265 series).
