Analog inputs

Important note
A channel requires a settling time of about 10 to 50 seconds after switching on. The
settling time in IEPE 1 Hz mode is shorter than in IEPE 0.1 Hz mode.
This also applies, if the signal was overdriven for a short time.
The analog inputs can be adjusted to different operating modes per channel. The oper-
ating mode is configured in ibaPDA.
 IEPE input (±5 V) with 1 Hz high-pass filter
 IEPE input (±5 V) with 0.1 Hz high-pass filter
 24 V AC input (AI)
 24 V DC input (AI)
4 inputs are adjusted permanently to IEPE mode. The mode of the second input of each
root can be configured: IEPE, 24 V AC or 24 V DC. The following table shows the possi-
ble settings:
Analog input 0
Analog input 1
Analog input 2
Analog input 3
