Frequently Asked Questions (FAQ)

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

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

How does the SM200-A connect to KROHNE IF300 instruments?

The SM200-A connects in series or parallel to the 4-20mA loop of the KROHNE IF300. It acts as a master/slave receiver to poll and display the primary variables transmitted by the KROHNE device via the HART protocol.

Is the SM200-A compatible with Rosemount pressure transmitters?

Yes, the SM200-A is fully compatible with Rosemount pressure transmitters (such as the 3051 series) and other standard HART protocol field devices, allowing real-time pressure value readouts.

Does the SM200-A display require an external power source?

No, the SM200-A is typically loop-powered directly from the 4-20mA current loop, which simplifies wiring and eliminates the need for an additional external power supply.

Can the SM200-A display multiple variables from a single HART device?

Yes, it can display primary variables (PV), current values (mA), percentages, and secondary variables depending on the configuration and capabilities of the connected HART instrument.
