Opto Coupler/Relays
A Opto-coupler is a electronic component that transfers electrical signals between two isolated circuits by using light. one of the important function is to prevent high voltages from affecting the system receiving the signal and have been used for a variety of applications, ranging from industrial equipment such as inverters,home appliances, air conditioners and power generation systems.
KEYSEMI database is offering extensive product range of various output configuirations
