Emerson 03031-0193-0103 LCD Meter Display Kit

Emerson 03031-0193-0103 / 03031-0001-0002 Communication and Display Module

The Emerson 03031-0193-0103 (often cross-referenced with variant base assembly 03031-0001-0002) is an engineered liquid crystal display (LCD) meter assembly designed for integration into core industrial field instruments. As a vital local operator interface (LOI) component, this communication and display module mounts directly onto the electronics board housing of high-accuracy pressure, differential pressure, and level transmitters. It translates internal digital bus communications into clear, real-time engineering units or percentage-of-span readouts. Engineered to withstand severe vibration, thermal extremes, and corrosive marine or offshore atmospheres, it ensures reliable local diagnostics without opening control loops or requiring portable HART communicators.

Frequently Asked Questions

Does the Emerson 03031-0193-0103 display module require separate power wiring?

No. The display unit draws its operational power directly from the host transmitter’s internal electronics board via the 10-pin data and power header. No external or separate power source is required.

Is this display compatible with both HART and FOUNDATION Fieldbus protocol transmitters?

This specific meter assembly is primarily engineered for standard 4–20 mA HART analog transmitters. Fieldbus and Profibus variants typically use distinct firmware-matched display part numbers. Verify your transmitter output card protocol before ordering.

Can I replace this display module in an active hazardous zone?

Replacement can be performed live only if the circuit is certified intrinsically safe and local hot-work safety permits are observed. For flameproof (Ex d) installations, power must be isolated and the area declared gas-free before removing the enclosure cover.

What should I do if the display shows configuration error messages upon startup?

An error code or unscaled reading typically indicates that the display needs to be re-zeroed or configured to match the specific calibration range of the sensor module using a HART configuration tool.
