FS500 SERIES

Description

The FS500 Series flash rate is adjustable from 10 to 100 FPM.

A locknut is provided to hold selected flash rate. The long-life

electronic circuit combined with a quality electromechanical

relay provides flexibility and reliability in most applications.

Operation

Upon application of input voltage, the output relay is energized

and the ON time begins. At the end of the ON time, the output

relay de-energizes and the OFF time begins. At the end of the

OFF time, the output is energized and the cycle repeats as long

as input voltage is applied.

Reset: Removing input voltage resets the output and

the sequence.
