Switch input/output channels and analog input and output channels and they are interference enter channels.The object and input/output public ground lines should be removed and interference pulse should be suppressed by realizing electrical isolati to cut off this channel.The most common isolation device is photoelectric couplers, its internal structure is shown as the above picture. Anti-jamming Circuit Principle Diagram with Four Analog Input Channels We have to notice that:When we use photoelectric couplers to isolate input output channel,all signals(digital quantity signals,control signal,condition siganl) should be isolated and it makes both sides isolation have no electrical ties.Otherwise,the isolation is meaningless.
