FAQ
Q: Does this module support HART communication?
A: Yes, it allows digital communication with smart field devices while reading 4-20 mA analog signals.
Q: Are the input channels isolated?
A: No, this model is non-isolated. Proper system design should account for potential ground loops.
Q: Can this module connect to AEA4D terminal boards?
A: Yes, the included ATK4A-00 KS Cable Interface Adapter provides direct connectivity.
Function Comparison
Compared to the Yokogawa AAI143 series, the AAI141-H00/K4A00 provides HART communication with non-isolated inputs. It is suitable for applications where isolation is not required but precise 16-channel signal acquisition and smart device interaction are needed.
