Claim 0:
1. A Transmitter for transmitting a process variable to a programmable logic controller, wherein in a current mode a 4-20 mA current is fed into a burden (1) and in a voltage mode 0-10 V signals are generated, comprising a process value input (2), a current stage (3), a voltage stage (4) and a U/I output (5) for the current or the voltage signal, and a U/I control input (6, 6a, 6b) for switching between the two modes, wherein
the transmitter is configured to feed a current which is dependent on the voltage across the burden (1) into the current stage (3) via a resistor (7) and thus to compensate for a current loss at the voltage stage (4) which is dependent on the voltage across the burden (1).
