What is the RIA15 process indicator?

The RIA15 is a loop-powered local display (process indicator) designed to show process signals (e.g. 4-20 mA) in the field or on a panel.
It can also support HART® communication to display additional sensor variables (up to four) when connected to HART-capable devices.
It is often used where you want a local read-out of an analog loop without needing a full controller or separate power supply.

Key specifications & features

Here are some of the notable technical and functional features of the RIA15:

Feature	Description
Input signal	1 × analog 4-20 mA (scalable)
HART support	Yes — can act as a primary or secondary HART master, read and display up to 4 HART variables (PV, SV, TV, QV)
Powering	Loop-powered; no separate external power supply required
Voltage drop in loop	≤ 1 V (for standard 4-20 mA mode) / ≤ 1.9 V (if using HART)
Display	5-digit LCD (digit height ~17 mm) + bar graph; backlight option
Housing / mounting	Available in panel mount or field (weatherproof / explosion-proof) versions
Configuration / operation	3 front keys for menu navigation & parameter setting; can be locked via passcode
Approvals / safety	Various certifications (ATEX, IECEx, FM, CSA, etc. depending on version)
Functional safety (SIL, safety use)	Some versions are “LA” type / SIL-certified. The device’s safety function is the faithful transmission of the 4-20 mA signal without distortion; the display is not part of the safety function.

How it works / modes of operation

In its standard analog mode, the RIA15 is inserted into the current loop (4-20 mA) and it measures the current, converts it to the configured engineering units, then displays that value locally.
In HART mode, the device can poll the sensor via the HART protocol and fetch additional variables (e.g. temperature, pressure, diagnostics) to display.
It can be either primary or secondary HART master. In a HART loop, typically there is one primary master (e.g. DCS / PLC) and optionally a secondary master (such as the RIA15) for local diagnostics
The display can alternate among different HART variables based on configuration (e.g. PV → SV → TV → QV).

Use cases & advantages

Local readout: Offers a way to visualize the loop’s process value right where the measurement is, without needing a full controller or remote display.
Low voltage drop: Because it introduces very little voltage drop (≤ 1 V or ≤ 1.9 V in HART mode), it is suitable even when the loop supply voltage is tight.
HART diagnostics: If your sensor is HART-enabled, you gain access to additional information (status, diagnostics, extra variables) via the indicator.
Flexibility: It can be panel-mounted or used in the field, and is configurable on-site with minimal tools.
Safety use: Where applicable, “LA” versions allow using the indicator as part of a safety instrumented system (SIS), with restrictions and proper proofs/tests.
