DS2621 Signal Generation Board 

HighFlex board for simulating ECU input signals  

The DS2621 Signal Generation Board stimulates ECU inputs. It mimics sensors or switches such as door contact switches, Hall sensors, and sensors for wheel speed and oil temperature. Each of the DS2621's 10 channels can be software-configured as a voltage source, a current sink, a digital output simulation or a resistance simulation.
