Optocouplers

An Octocoupler, also known as an opto-isolator, photocoupler, or optical isolator is an electronic device that transfers electrical signals between two isolated circuits via light. Optocouplers are designed to prevent damaging high voltages from affecting the system receiving the signal.

An opto-isolator contains a light emitting source, generally an infrared LED, that converts an electrical input signal into light, a closed optical channel and a photosensor, which detects incoming light and either generates energy or modulates current from an external power supply.

An Optocoupler connects input and output sides with a beam of light modulated by input current. It transforms input signals into light, sends it via the dielectric channel, captures light on the output side transforming it back into electric signal. Typical examples of Optocouplers include Resistive opto-isolators, Photodiode opto-isolators, phototransistor opto-isolators and bidirectional opto-isolators.

Kempston Controls stocks a wide range of Optocouplers from leading brands such as ABB, Honeywell, MURR and Siemens. Give our sales team a call on +44 (0) 1933 411411 or use the contact form above to discuss your Optocoupler requirements.
