Page 8: Section 3 How To Dismantle Drst-Ur
Section 3.2 - When front LED lights red / display shows AO.ER Omega DRST-UR is designed as a SIL 2 device with a high safety level. Therefore, a continuous measurement of the outgoing current is carried out on a 4...20 mA and 20...4 mA output signal. If the current output signal is different from the internal calculated output value or the current output is 0 (due to e.g. -
Page 9: Section 4 Features
• Process control with 2 pairs of potential-free relay contacts and analogue output. • Galvanic separation of analogue signals and measurement of floating signals. • The DRST-UR is designed according to strict safety requirements and is thus suit able for application in SIL 2 installations. -
Page 10: Section 5 Display Characteristics
Section 5.2 - Application • Communications interface for modification of operational parameters in DRST-UR. • Can be moved from one DRST-UR device to another and download the configuration of the first transmitter to subsequent transmitters. • Fixed display for readout of process data and status. -
