Bipolar Isolation Amplifier DB 68Isolation and Conversion of Fixed Range Bipolar and Unipolar Standard SignalsThe Isolation Amplifier DB 68 is used for isolation and conversion of bipolar and unipolar standard signals. For applications where one signal combination only is used, the Isolation Amplifier DB 68 offers a cost-effective alternative. A cross-connector for the auxiliary power supply ensures fast and easy installation. The slim housing with 1 1.2 mm width saves significant space on the DIN-rail. If required a measuring range compensation can be performed at the Zero/Scan potentiometers behind the front cover. Analog signal processing guarantees precise measured values with short response times and outstanding signal reproduction at the output. Protective Separation and the 24 V AC/DC power supply make the DB 68 universally applicable for all measurement and industrial applications, as well as for building automation. • Cost optimized design Economical separation for standard applications • Only 60 mm installation depth, 11.2 mm wide Can be installed in economical standard terminal boxes • Fixed ranges, easy to use Ready to use without any settings or adjustments • Zero/Span compensation on front panel for readjustment of sensor signal or measuring equipment • True 3-port separation Protection against erroneous measurements due to parasitic voltages or ground loops • Protective Separation acc. to EN 61140 Protects service personnel and downstream devices against impermissibly high voltage • Unlimited use with 24 V AC/DC power supply Universally applicable for all measurement and industrial applications • 5 Years Warranty Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender) DRAGO Signal Converter - Isolation Amplifiers - www.drago-automation.de
