The DRST-DC is a DIN rail-mounted signal conditioner designed for universal unipolar or bipolar DC current and voltage measurement. It provides passive or active current buffered output voltage with an electrical output range of 0 to 23 mA. Featuring a bandwidth greater than 40 Hz, power consumption of 2.5 W, and IP20 enclosure rating, it requires an additional programmer for configuration. UL and RoHS approved.

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.
