Analog inputs
Figure 4-9
Characteristic of analog inputs (see also Auto-Hotspot):
● The input signal is an analog current (standard 0 ... 20 mA, maximum 30 mA)
● The signal current must be provided by an external current source
● Load (internal resistance) of analog input: 10 Ω
● Reference potential GND (see Fig. of analog inputs)
● Overcurrent protection: ±1 000 mA
● Max. voltage: ±50 V
Function
The analog inputs (AI1, AI2) need only be connected if these inputs are configured in the
analyzer. The corresponding information is supplied separately in this case.
● Therefore check the delivery to see whether information on the analog inputs has been
● If this is the case, connect the specified signal sources to the analog inputs.
