  • Transmitter for transmitting a process variable to a programmable logic controller
    Patent number: 11949227
    Abstract: The invention relates to a transmitter for transmitting a process variable to a programmable logic controller. In a current mode a 4-20 milliamp current is fed into a burden and in a voltage mode 0-10 Volt signals are generated. The transmitter includes a process value input, a current stage, a voltage stage and a U/I output for the current or the voltage signal, and a U/I control input for switching between the two modes. The transmitter is configured to feed a current which is dependent on the voltage across the burden into the current stage via a resistor and thus to compensate for a current loss at the voltage stage which is dependent on the voltage across the burden.
