Temperature measurement analog signal transmitter DRST-UR

DIN rail4-20 mA0-20 mA

• Input for RTD, TC, Ω, potentiometer, mA and V • 2-wire supply > 16 V • Output for current, voltage and 2 relays • Universal AC or DC supply • UL and cUL Approval Advanced Features Programmable via detachable display front, process calibration, signal and relay simulation, password protection, error diagnostics and selection of help text in several languages. Application • Linearized, electronic 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 2 pairs of potential-free relay contacts and analog output. • Galvanic separation of analog signals and measurement of floating signals. • The DRST-UR is designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations. Technical Characteristics • When DRST-UR is used in combination with the DRSL-DISPLAY programming front, all operational parameters can be modified to suit any application. As the DRST-UR 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. A yellow LED is ON for each active output relay. • A continuous check of vital stored data for safety reasons. • 4-port 2.3 kVAC galvanic isolation.
