AJMRTC 8-channel optocoupler isolation detection module adopts optoelectronic isolation technology. It can detect AC 220V signals and convert them into TTL level signals output, which can be directly read by single-chip microcomputers, PLC processors and other control units. The optocoupler isolates high-voltage AC side and low-voltage control side, preventing high voltage from damaging the rear-end control circuit.
There are 8 independent detection channels to realize multi-channel AC signal status monitoring. The module uses terminal block wiring for convenient installation. It is widely used in industrial signal detection, equipment status feedback, power monitoring, PLC input expansion and other industrial control projects.
