Process value indicators with LED display

Displays are used in industrial and process automation for the visual display of
data or for the analogue presentation of electrical and non-electrical measurement values.
They are an important tool for user prompting, diagnostics and logging
when operating machines and systems. Displays support dialogue-based operation, display measured values and  fault reports, and are used to monitor
processes.

Features, such as the internal calculation of process variables, digital and analogue outputs
or interference suppression functions upgrade simple displays to high-quality
process interfaces which can independently control sub-processes .
