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 display range and the 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” is freely programmable.
With this field indicator it is possible to display range alarms as well as minimum and maximum values. Error-current signals from the connected transmitters are also detected and displayed. The field 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.
They can be mounted directly onto a wall. An optional pipe-mounting kit for mounting to pipes with a diameter of 1 ... 2" is available.
The models DIH5x-B, DIH5x-Z display modules are also available separately for installation into other suitable cases.
The field indicators consist of a field case made of aluminium or stainless steel with a built-in display module.
