Optocoupler relays provide isolation between the control signal and the load. These compact DIN rail mounted relays are available with load voltages up to 250 VAC/48 VDC, current ratings up to 10A, and an integrated LED display. MOSFET, transistor, or TRIAC output options are available.
Optocouplers are used to convert 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 the input and output. Optocouplers 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 period of time.
