9Characteristics 4Section 4.1 - Universal Transmitter DRST-UN• Input for RTD, TC, Ohm, potentiometer, mA and V• 2-wire supply > 16 V• Output for current and voltage• Universal AC or DC supply4.2 - Advanced FeaturesProgrammable by way of detachable display front DRSL-DISPLAY, processcalibration, signal simulation, password protection, error diagnostics and helptext available in several languages.4.3 - Application• Linearised, electronic temperature measurement with RTD or TC sensor.• Conversion of linear resistance variation to a standard analogue current /voltage signal, i.e. from solenoids and butterfly valves or linear movementswith attached potentiometer.• Power supply and signal isolator for 2-wire transmitters.• Process control with standard analogue output.• Galvanic separation of analogue signals and measurement of floating signals.• The DRST-UN is designed according to strict safety requirements and is thussuitable for application in SIL 2 installations.4.4 - Technical characteristics• When DRST-UN is used in combination with the DRSL-DISPLAY display/programming front, all operational parameters can be modified to suit anyapplication. As the DRST-UN 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.• 3-port 2.3 kVAC galvanic isolation.
