Available in 5V, 6V, 12V & 24V dc relay coil versions, these handy little relay boards use a small PCB to carry a mains rated SPDT relay with Common, Normally Open and Normally Closed connection options.
Electrical isolation is provided solely by the relay coil /contact interface (see relay datasheet for specifications). If your application requires a greater degree of electrical isolation then we recommend you use one of our opto-isolated relay boards instead.
The board includes a back-emf protection diode across the relay coil.
See order code 8045KT for a 2 channel version of this product.
