The process indicator supports the 4...20 mA or HART® protocol. Using the HART® protocol, it can alternately display up to 4 measured values of one sensor and can be set as a HART® master or secondary master to acquire data from the sensor. The device is a one-piece design that can be field-mounted or panel-mounted and is suitable for a wide range of applications. Especially in Ex applications, voltage drop: <1V (< 1.9V (HART®)
Advantages
4...20 mA measured value display or selective display of 4 HART® process variables of one sensor, suitable for all industries; can be used as HART® master or secondary master
5-digit measured value display, character height: 17 mm (0.67"), including size and bar graph, backlight can be activated
Local display can use a panel-mount housing (IP65) or a field housing (IP66; Ex approval); minimal installation depth
No external power supply required; voltage drop ≤1 V (HART® ≤1.9 V)
3-key operation for simple device setup
International approvals; marine approvals
SIL immunity approval in accordance with EN 60508
Application areas
Can be used in any industrial application to display 4-20mA measured values or HART® process variables
Panel-mount or field housing with field display
Scalable display values
The “level” or “analysis” options allow basic setup of selected sensors and quick, easy setting of available measured values and units.
