Optocoupler relays serve industrial applications where electrical isolation between the control signal and the load is important. These compact 6.2mm DIN rail mounted relays are available with load voltages of up to 250 VAC/48 VDC, and up to 6A ratings; integrated LED indicators display status. MOSFET, transistor or TRIAC outputs options are available.
Murrelektronik optocouplers and semiconductors are used to combine different signal levels or to isolate one signal from another. They are similar to a relay interface because they provide an optoelectronic signal transfer between input and output. Optocouplers and semiconductors have a long life span because they don't have any mechanical components that could wear out. They are suitable for applications with high switching frequencies, even over a long time.
