The DIH series field indicators are 4 ... 20 mA current loop indicators which can, in addition, offer a superimposed HART communication between the connected transmitter and the control room. Thus, the indication range and units are automatically adopted depending on the settings of the connected HART transmitter.
Common units for temperature and pressure are already saved ex works. An additional User unit can be programmed optionally.
With this field indicator, it is possible to display range alarms as well as MIN and MAX values. Error-current signals from the connected transmitters are also detected and displayed. The indicator can be used in conjunction with any 4 ... 20 mA transmitter.
The field indicators are powered directly from the 4 ... 20 mA current loop, with a resultant voltage drop of less than 3 V.
The field indicators can be mounted directly onto a wall. An optional pipe mounting kit is available for fitting to pipes with a diameter of 1 ... 2".
The models DIH5x-B and DIH5x-Z basic modules are also available separately for mounting into other suitable cases.
The field indicators consist of an aluminum or stainless-steel field case with a built-in display module.

Q & A
Field Indicator with HART? Communication Models DIH50 and DIH52 Q & A
The WIKA Field Indicator Models DIH50 and DIH52 are rugged, loop-powered instruments designed to display process values from 4–20 mA current loop transmitters with HART? communication. They extract and display real-time data such as pressure, temperature, flow, or level directly from the field transmitter while supporting HART digital signals for flexible configuration and diagnostics.
- DIH50: Standard field indicator with automatic range adoption via HART
- DIH52: Adds HART secondary master functions and multidrop capability
HART? communication superimposes digital data on the standard 4–20 mA signal, allowing the indicator to automatically read measuring ranges, units, and status information directly from the connected HART transmitter. This means you get more accurate displays, configurable units, richer diagnostics, and easier setup without additional power supplies or wiring.
Key benefits:
- Automatic range and unit adoption
- Display of alarms, MIN/MAX values, and error signals
- Remote configuration through HART masters
- Secondary master and multidrop support (DIH52)
These WIKA indicators are suitable for industrial process environments, including:
- Process engineering and plant construction
- Oil & gas facilities
- Water and wastewater plants
- Manufacturing and power generation facilities
They mount easily on walls or with optional pipe kits (1–2″ diameter) and work with almost any 4–20 mA transmitter thanks to a universal loop-powered design.
Key display characteristics include:
- Large multi-digit LCD range display (-9999 to 99999)
- Bar graph visualization for trend and range clarity
- Status and unit messaging are shown on the display
- MIN/MAX and alarm indication from the HART transmitter
- Optional user-defined unit programming
These features make it easier for operators and technicians to interpret field data quickly and accurately on site.
The DIH50/DIH52 field indicators are powered directly from the 4–20 mA loop (voltage drop < 3 V), so no separate power source is needed. They are designed for wide compatibility with standard process transmitters and can connect anywhere in the loop for remote local display.
- Optional configurations and versions include:
- Intrinsically Safe (I) and Flameproof (F) enclosures for hazardous areas
- Mounting kits and basic indicator modules for custom panel builds
