Optocoupler is ideally used to intersect with an electric signal into dual isolated circuits by using optimal quality of light. It aids to protect from extreme voltage from interrupted signal error. It is used in fragile system between compacts sensor and PLC devices. Optocoupler is adjustable in varied monitoring lighting system, communication, and control panel system. It is easy to maintain and fixed in heavy duty appliances. Therefore, provided gamut is packed in a water proof and lead proof packaging.
