Universal transducer WK121
processes resistance signals, current and voltage / no additional power required / compact dimensions / galvanic insulation / settings are performed by means of the software

The universal transducer WK121 is a device for universal usage. This device can convert thermo-elements signals, resistance temperature sensors, potentiometers as well as both current and voltage signals into 4 … 20 mA signal. The universal transducer WK121 is directly powered by the power supply loop. Some of our digital displays, as for instance the N30U, use this kind of power supply. The use of the universal transducer WK121 combined with a digital display can solve a lot of problems. The compact dimensions (only 6.2 mm width) of the universal transducer WK121 are one significant advantage. The universal transducer WK121 is set by means of the optional software. Here you will find an overview of the universal transducer that best suits your needs.
