Frequently Asked Questions

What is the main function of the SM200-A HART Data Display?

The SM200-A HART Data Display is designed to read and display process variables directly from HART-compatible smart instruments (such as pressure, temperature, or flow transmitters) without interrupting the 4-20mA loop signal.

How does the SM200-A interface with KROHNE IF300 instruments?

It connects in series or parallel to the 4-20mA HART loop of the KROHNE IF300. It polls the instrument's HART data to display real-time measurements on its screen.

Can the SM200-A work with Rosemount pressure transmitters?

Yes, the SM200-A is fully compatible with Rosemount pressure transmitters (like the 3051 series) and other standard HART protocol devices.

Does the SM200-A require an external power supply?

The SM200-A is typically loop-powered from the 4-20mA current loop, requiring no external power supply for basic operations, making installation simple.

What parameters can the SM200-A display?

It can display the primary variable (PV), current value (mA), percentage, and secondary variables supported by the connected HART instrument.

Where can I access the wiring and application diagrams for these setups?

You can access the detailed application diagrams via the links provided in the resources section above for both KROHNE and Rosemount configurations.
