DS2601 Signal Measurement Board

HighFlex board for measuring ECU output signals

The DS2601 is used in a SCALEXIO hardware-in-the-loop simulator. It provides current and voltage measurement during HIL tests of ECUs. It includes fuses that can be configured via software. The DS2601 can be equipped with on-board loads or external loads via a second connector. 

Application Area

The DS2601 Signal Measurement Board measures ECU output signals and passes the measurement values to the real-time processor. Signal measurement can be time-triggered or event-triggered, and the execution of signal measurement can be voltage- or current-triggered.


I/O Functionality

The DS2601 has 10 flexibly configurable input channels, which can connect analog (analog-digital converter) and also digital (comparator) measurement units to measure the current and voltage. For example, the measurement units can be combined to trigger analog current measurement if a specified voltage is exceeded. The channels are defined and configured in the ConfigurationDesk® software. The 10 channels on the DS2601 can be connected in parallel. This channel bundling increases the current carrying capacity up to 80 A (RMS). ConfigurationDesk displays the bundled channels as one single I/O function. The DS2601 supports the use of loads for the ECU. You can either plug substitute loads onto the board itself or connect real loads via a cable harness to the externally accessible load connector.
