Technical FAQ
Q: What is the difference between the H00 and K4A00 suffixes?
A: H00 indicates the standard functional specification. K4A00 defines connector and environmental protection options, typically including conformal coating for resistance to corrosive gases.
Q: Does this module support HART communication?
A: The AAI841-H00/K4A00 is designed for analog signal processing only. HART functionality depends on the terminal board and system configuration and should be verified separately.
