The intelligent signal isolator is suitable for various signal isolation occasions.

Description

technical field [0001] The invention relates to an intelligent signal isolator, belonging to the technical field of signal isolators, in particular to a digital intelligent signal isolator with high reliability. Background technique [0002] The analog signal isolator can perform high-speed and accurate measurement of electrical parameters such as current and voltage or non-electrical parameters such as temperature and resistance. After isolation, it can be converted into a standard analog signal output. Matching with automatic control instruments (such as PLC), various A / D converters and computer systems, it is widely used in automation systems in electric power, railway, petrochemical, metallurgy, chemical, food, storage and other industries. [0003] Due to the different adjustment gain of the signal isolator, there are many kinds of existing signal isolators, most of which use potentiometers to adjust the gain, which has poor reliability, and the general optoelectronic i...
