    ITUWA - N-110-2 Resistive Neon OptoIsolator, Photoconductor, Photoresistor, or Vactrol. Resistive Opoto-Isolator (RO), also called photoresistive opto-isolator, or Vactrol. Analog opto-isolator or lamp-coupled photocell, is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically isolated from each other. An Opto-Isolator is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal.
