Description

technical field [0001] The invention belongs to the field of digital quantity output, in particular to a novel digital quantity output circuit. Background technique [0002] At present, the commonly used digital output circuits only include the drive and photoelectric thyristor circuits, and there is no detection circuit and mixed line protection circuit, so the circuit itself does not have the channel self-test function. Misoperation and refusal to operate, and it does not have the function of mixed line protection, which may easily cause equipment misoperation. Contents of the invention [0003] The purpose of the present invention is to provide a digital quantity output circuit which can eliminate the malfunction and refusal of the control equipment, and has the protection function of mixed lines. [0004] The technical solution of the present invention is: a novel digital quantity output circuit, including a driving circuit A5 connected in series with a photoelectric ...
