The large backlit display of the indicator shows the measured values, optionally as a bar graph for a faster process overview. Editable plain text can display engineering units or TAG information. If a limit value is exceeded, a signal is emitted and the open collector is activated. The indicator does not require a separate power supply and is powered directly via the 4...20 mA loop. The housing is made of pure aluminum or stainless steel, with optional Ex d approval.
Benefits
4...20 mA measured value display
5-digit measured value display including dimension, bar graph and backlighting
No external power supply required
Versions: die-cast aluminum housing or stainless steel housing
Simple 3-key operation; or operation via FieldCare PC software; or via setup frame without power supply
International approvals; marine approvals
Allows free passage of the HART® transmission protocol
Applications
The display unit is equipped with a field instrument housing and a microcontroller with an LC backlit display. The display of measuring range, decimal point and offset can be easily configured via 3 keys after opening the housing, or on a PC via the FieldCare PC software.
