A programmable resistor is designed to emulate the use of resistive sensors and variable resistors in systems when testing devices such as engine controllers.
Resistor chain used in a typical programmable resistor
Pickering's programmable resistors in their simplest form consist of a basic chain of resistance values switched in or out of the 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.
