Programmable by way of
detachable display front (PR 4501), process calibration, signal simulation,
password protection, error diagnostics and help text available in several
temperature measurement with RTD or TC sensor.
Conversion of linear resistance
variation to a standard analog current / voltage signal, i.e. from solenoids
and butterfly valves or linear movements with attached potentiometer.
Power supply and signal
isolator for 2-wire transmitters.
Process control with standard
Galvanic separation of analog
signals and measurement of floating signals.
The PR 4114 is designed
according to strict safety requirements and is therefore suitable for application
in SIL 2 installations.
When PR 4114 is used with the
PR 4501 display / programming front, all operational parameters can be modified
to suit any application. As the PR 4114 is designed with electronic hardware
switches, it is not necessary to open the device for setting of DIP-switches.
A green / red front LED
indicates normal operation and malfunction.
Continuous check of vital
stored data for safety reasons.
