Technical FAQ

How does the 10 kHz sampling rate benefit my process?
The 10 kHz sampling rate enables high-resolution monitoring of rapidly changing process variables, reduces signal aliasing, and ensures accurate transient signal capture for control system processing.

Is the module compatible with 4–20 mA HART transmitters?
Yes. The 0–20 mA input range fully supports standard 4–20 mA HART instrumentation signals, maintaining high measurement accuracy even when digital HART communication is superimposed on the analog loop.
