2 / 3-point controller for control and/or supervision of temperatures existing in liquid or gasiform media with decimal display of set/ actual value for front panel installation. Suited for use as digital remote controller in industry and agriculture and the machine building and apparatus engineering sphere. The controllers are equipped with a serial interface. Cross-linking and data acquisition is possible via PC. The connection to an RS 232 interface is possible only when using an appropriate interface connector. Especially our standard signal measuring transducers are qualified for use with the controller model JUD-210. In this case, the measuring transducer itself will determine the corresponding physical value.
