DescriptionOMEGA’s SSRINT660 Series “Intelligent” Solid State Relays are fully integrated with heat sink and DIN rail mounting plate in a space-saving design. They are touch-safe with LED input indication. All units come with built-in, replaceable semiconductor fuses. LED’s indicate fuse failure. These “intelligent” relays automatically shut down when in over-temperature conditions. When returned to normal operating temperatures, the relay will turn back on. “Intelligent” relays are single pole, normally open devices, capable of millions of cycles of operation. Dual SCR’s provide a high level of reliability.
