The Resistance Transmitter DER 41 converts the sensor resistance value to a standard signal and makes it galvanic isolated available on output.
For applications where one measuring range only is used, the Resistance Transmitters DR 41 offers a cost-effective alternative.
A cross-connector for the auxiliary power supply ensures fast and easy installation. The slim housing with 11.2 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 DR 41 universally applicable for all measurement and industrial applications, as well as for building automation.
