DIH50 / DIH52 Field Indicator

The WIKA DIH50 / DIH52 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 dependent 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 WIKA DIH5x-B, DIH5x-Z basic modules are also available separately for mounting into other suitable cases. The field indicators consist of an aluminium or stainless steel field case with a built-in display module.
