Phoenix Contact 2954235 Solid State Relay Module 24V DC / 280V AC 3A

The optocoupler, also known as opto-isolator, photocoupler, or photo-electric coupler, with type number EMG 17-OV- 24DC/240AC/3 from Phoenix Contact is an electrical component for potential separation and signal transmission in electrical circuits. It has dimensions of 15 x 10 x 10 cm and a weight of 0.1 kg. Optocouplers enable the transmission of electrical signals between two galvanically isolated circuits using light, ensuring safe isolation while allowing information exchange. This protects sensitive components from overvoltages, interference, and common-mode noise. Typical applications include the control of power electronics and motors in automation technology, as well as signal decoupling in measurement systems and communication interfaces.
