MDSB345E series potentiometer transmission Isolated Safety gate The power supply circuit. The receiving of dangerous places (slide wire potentiometer) signal, after the isolation process, transform into linear resistance Two Wire current signal output. The output circuit of power supply, power does not need to work independently. Optional One enter One A. Isolated gateFrom the terminal energy into the limit of intrinsically safe dangerous places, so as to ensure the safety and explosion-proof system.
