Isolated gate of intelligent voltage current input operation end

An isolated gate of an intelligent voltage current input operation end is applicable to the signal measurement and isolated output of electrical equipment in dangerous industrial places and commonly forms an intrinsic safety explosion-proof system with an intrinsic safety type explosion-proof device installed in the dangerous places. The isolated gate isolates and outputs a safety zone signal to a dangerous zone and drives an executing mechanism and other devices on the spot. The isolated gate of the intelligent voltage current input operation end includes: a power circuit, an energy limit protection circuit, a signal sampling circuit, a CPU control part, an optical coupling isolation circuit and an output circuit and is characterized in that: the signal input end is sequentially connected with the signal sampling circuit, the CPU control part, the optical coupling isolation circuit and the output circuit and then outputs to a dangerous side through the energy limit protection circuit.
