5.6.4 Current measurement
·
Current: ±40 mA, ±20 mA, ±10 mA ... ±1 mA in 6 ranges
A special plug (ACC/DSUBM-I4) with a built-in shunt (50 Ω) is needed for current measurement.
For current measurement with the special shunt-
plugs ACC/DSUBM-I4, inputs ranging only up to
max. ±50 mA (corresponding to 2 V or 2.5 V voltage
ranges) are permitted due to the measurement
shunt's limited power dissipation in the case of
static long-term loading.
Since this procedure is a voltage measurement at the shunt resistor, voltage measurement must also
be set in the imc Software.
The scaling factor is entered as 1/R and the unit as A (e.g. 0.02 A/V = 1/50 Ω).

5.6.5 Bandwidth
The channels' max. sampling rate is 100 kHz (10 µs). The analog bandwidth (without digital low-pass
filtering) is 11 kHz (-3 dB).
5.6.6 Connection
For signal connections, DSUB-15 connectors can be used.
Please find here the DSUB-15 pin configuration .
