Description
|
|
|
The DIH series field displays 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 scale range and units are automatically adopted dependent on the settings of the connected HART® transmitter.
Common units for temperature and pressure are factory-set. An additional "user unit" is freely programmable.
With this field display 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 display can be used in conjunction with any
4 ... 20 mA transmitter.
|
The field displays are powered directly from the 4 ... 20 mA current loop, with a resultant voltage drop of less than 3 V.
The field displays 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 model DIHxx-B basic modules are also available separately for mounting into other suitable enclosures.
The model DIH5x field displays consist of an aluminium field case with a built-in basic module.
The model DIH62 digital displays are available with various case materials, such as plastic, stainless steel and aluminium.
