The Temperature Transmitter IS 48 converts the sensor signal on input to temperature linear standard signal and makes it galvanic isolated available on output.
For applications where one measuring range only is used, the Temperature Transmitter IS 48 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 Temperature Transmitter IS 48 universally applicable for all measurement and industrial applications, as well as for building automation.
