FIELD: transmitters of industrial process parameters.
SUBSTANCE: transmitter of process parameter contains: connections, which connect and disconnect with additional load, transmitter circuit, receiver circuit, power limiter circuit, setting first powering current limit and providing for outlet of stored energy, recessive exciter circuit, draining excitation current from stored energy outlet and feeding excitation current onto serial bus, and also setting limit for excitation current, circuit of dominant exciter, in main state conducting excitation current to common conductor, and in inactive state excitation current is only accessible when additional load is present.
EFFECT: decreased power consumption.
