Overview

The Littelfuse FS512 is a DPDT adjustable flasher relay designed for industrial and automotive applications requiring cyclical load switching. This electromechanical relay combines solid-state timing circuitry with a high-reliability output stage, offering an adjustable flash rate from 10 to 100 operations per minute (FPM) with a fixed 50% ON/OFF ratio. The unit operates on 12VDC input with reverse polarity protection and provides 10A resistive switching capability at 28VDC and 120/240VAC, plus 1/3 hp motor load handling at 120/240VAC. Its octal 8-pin plug-in mounting design simplifies installation and replacement in control panels. The FS512 measures 3.62 x 2.39 x 1.78 inches (91.6 x 60.7 x 45.2 mm) and weighs approximately 5.8 oz (164 g). The adjustable flash rate allows precise timing control for indicator lights, warning systems, or automated processes. The unit resets automatically upon input voltage removal and operates reliably across -20°C to 60°C with storage from -30°C to 85°C. Ideal for applications requiring repetitive cycling of resistive or motor loads, the FS512 provides dependable performance in demanding environments.

DC Input Solid State Relay, 1 Form A SPST-NO, 18 – 32 VDC Input, 3 – 60 VDC Output, 3 A Contact Rating, DC Output, Board Mount, Red. An SSR, or Solid-State Relay is an electronic switching device that functions similarly to an electromechanical relay but with no moving contacts. It works by employing semiconductor switching elements like triacs, thyristors, and diodes. Solid State Relays are designed for applications that require high switching speed and feature low switching acoustical noise and extremely long life. These relays are used when direct control by electronic circuits is necessary and switching without arcing or contact chatter is required. SSRs are not a replacement but complement electromechanical power relays
