Summary:The utility model relates to an optoelectronic isolating type power switch circuit with 8 channels, comprising a protection circuit with confined amplitude, optoelectronic isolating circuit, pushing protection circuit, RC snubber circuit and power switch circuit. The inner circuit integrates the 8 channel switches together, in which 4 input channels control one output each and another 4 channels control 2 outputs each. The utility model adopts thick film layer, bared chip assembling, surface mount, and DIP full sealed metal packing structure, which supplies a method to integrate the 8 channel switch together to reduce the volume greatly and increase the performance. optoelectronic isolating eliminates the interference between output and input. With flexible and easy installation and application, the optoelectronic isolating type power switch circuit with 8 channels can be used under severe conditions.
