Optocoupled 4 relays board
This 4 Relay Optoisolated board has been designed to be interfaced with Microcontroller Modules and can be driven, in general, by TTL level signals. The inputs are optically isolated to ensure safety and reliability of operation in all control applications in the industrial and home automation fields. The quality of construction is excellent and suitable for professional applications for continuous use.
