DS2621 Signal Generation Board

HighFlex board for simulating ECU input signals

The DS2621 is used in SCALEXIO hardware-in-the-loop simulators. It provides signal generation for simulating voltages, currents, resistances, and switches during HIL tests of ECUs. Its current and voltage range can be increased by bundling up to 10 channels.  

Application Area

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.

Key Benefits

The DS2621 offers 10 versatile, software-configurable output channels that can be connected in parallel or in series to increase the current or voltage range. The board also includes an onboard failure routing unit.

I/O Functionality

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 and can generate time- and frequency-dependent signals (such as PWM). For example, the resistance simulation can be used to pass the specified temperature changes to an ECU via the environment model.

Channel bundling is supported by the software. ConfigurationDesk displays the bundled channels as one single I/O function.
