MDSB305E series Transmission isolation type potentiometer Safety gate The receiving of dangerous places (slide wire potentiometer) signal, after the isolation process, transform into a linear voltage or current signal output and resistance.Optional One enter One A, One enter Two A. Isolated gate From the terminal energy into the limit of intrinsically safe dangerous places, so as to ensure the safety and explosion-proof system.
