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.
 
• Input for RTD, TC, O, potentiometer, mA and V
• 2-wire supply 16 V
•  UL and cUL Approval
• Output for current, voltage and 2 relays
