Expansion Board E-Mobility

The Expansion Board E-Mobility extends the functions of the µLC Test System with typical sensor signals from the e-mobility sector. This includes resolver signals, strand current signals, incremental encoder signals, and a 30 V-DAC.

All inputs and outputs are short-circuit protected against ground and supply voltage.
