HighFlex I/O board for simulating ECU inputs
- Signal generation for simulating voltage, current,
resistance and switches
- Channel bundling to increase output voltage
- On-board failure routing unit
- Galvanically isolated channels
The DS2621 Signal Generation Board stimulates ECU inputs. It mimics switches and sensors 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 or a resistance simulation.
The DS2621 has 10 flexibly configurable output channels to make analog and digital signal generators available. To increase the current or voltage range, up to 10 channels can be bundled in parallel or in series. For example, two voltage sources can be switched in sequence, or two current sinks in parallel, to increase the output voltage or current. The digital output can be used as a switch, for example, for voltage or current sources. It can also generate time- and frequency-dependent signals (such as PWM). The resistance simulation includes factors such as resistance changes due to temperature fluctuations.
Channel bundling is fully supported by the software. ConfigurationDesk® displays the bundled channels as one single I/O function.
