DC filtering

DC filter

• Cutoff frequency (−3 dB) : 10 Hz ±3.5 Hz

Note: The high-pass filter is used to configure a dynamic input for an AC only input signal with one of 3 different 

cutoff frequencies. This filter can be disabled in order to allow the DC-coupling of the input signal (AC + DC)

provides a suitable diagnostic signal (DC bias level), for example, 

measurement chains using IPC707 or IQS900 signal conditioners.

open-circuit or short-circuit.

Unpowered sensors – line-fault detection of conditions such as

open-circuit.
