Professional FAQ
What signal type is best for noisy plants?
4–20 mA signals offer better noise immunity.
Is this module suitable for turbine protection?
Yes. It is designed for critical turbine applications.
How can I avoid false alarms?
Use alarm delays and proper hysteresis settings.
Can voltage and current inputs be mixed?
Yes. Each channel works independently.
When should I choose A6620 instead of vibration cards?
Use A6620 for process values like temperature or pressure.
