Littelfuse SSAC FS524 Flasher Relay 24V AC/DC + Young NDS 8 Octal Socket

Fully Functional ● 2019 Date Code ● Octal Socket Included

Littelfuse SSAC FS524 adjustable solid-state flasher relay, paired with a Young Electronics NDS 8 8-pin octal socket. The relay cycles its DPDT output ON and OFF at a user-adjustable flash rate of 10 to 100 FPM (flashes per minute), set via a screwdriver-adjustable knob with a locknut to hold the chosen rate. Operates from either 24V DC or 24V AC (50/60 Hz). Output rated 10A resistive at 120/240V AC. Fully functional and in very good condition. Ready for immediate use.

What You Receive: 1 FS524 flasher relay plus 1 Young Electronics NDS 8 octal socket (UL/cUL listed, 10A 600V) — ready to wire and deploy.

Application: Adjustable flasher relays are commonly used in tower obstruction lighting (FAA-required flashing red lights on tall structures, cell towers, smokestacks), industrial warning beacons, annunciator panels for alarm signaling, animated signage, and any application requiring a switched output that cycles at a controlled rate. The DC input variant is reverse-polarity protected. The on/off duty cycle is approximately 50% (equal time on, equal time off).
