Littelfuse, Inc. Time Delay Relays FS324

The FS324 is a solid-state time delay relay designed for 24VDC applications with a maximum current load of 1.5A. It features a fixed flash rate of 75 flashes per minute (FPM) and can be customized for flash rates ranging from 60 to 150 FPM. The relay operates in a continuous duty cycle, with an ON/OFF ratio of approximately 50%. Its two-terminal series connection allows for straightforward installation, making it suitable for both new and existing applications. The encapsulated design provides protection against shock, vibration, and humidity, enhancing reliability and longevity. The FS324 is particularly well-suited for moving vehicle applications due to its high immunity to line noise and transients. It can directly operate incandescent or resistive loads and has a surge current capability of up to ten times the steady-state current. The operating temperature range is from -20¬8C to 60¬8C, with storage capabilities from -40¬8C to 85¬8C.
