Circuit that reduces the numbers of components needed to transmit data from intrinsically safe to non-intrinsically safe circuits using opto-couplers |
摘要 |
The described circuit is an intrinsically safe circuit configured for supplying intrinsically safe power from a power supply in a hazardous environment. The intrinsically safe circuit reduces a number of node connections by reducing a number of components. The intrinsically safe circuit comprises an opto-coupler circuit configured for receiving a control signal, a resistor, and a single voltage limiting circuit. The reduction in components and node connections results in a reduction of board costs and area, while maintaining a desired level of protection.
