About Relays

With no moving parts, these solid state relays have an extended service life. Mount them directly to 35 mm DIN rail. They have an integrated heat sink that disperses heat to provide optimal convection cooling. An LED indicator tells you if they are open or closed. Relays are rated for continuous operating duty. They do not switch DC loads.
