off/on cycle as long as po wer is applied to the input terminals. Two knob operated potentiometers provide user
adjustment of both the flash rate and duty cycle. Contact rating:10 Amps @ 240V AC resistive. Operating temp.
range: -45 C to +70 C. Mounting:8-pin octal style plug. Spade terminal style a vailable. Timing tolerance:fixed
units +/- 5%, adjustable units 0 to + 10% of maximum specified delay time, minimum.specified delay time at low
end.Repeatability:+/- 1%. Reset:Upon interruption of power. Timing cycle interrupt transfer: None.

HDFA Series Recycling Timers
The HDFA Series low cost adjustable recycling timers are packaged in the familiar hockey-puck
enclosure and may be used to alternately switch power to two independent loads . Both OFF and
ON times are independently adjustable by means of built-in potentiometers. Load power is con-
trolled by an isolated SPDT relay contact.Timing ranges are adjustable of a 100:1 span and cover
0.25 seconds to 100 minutes. Contact Rating:10 amperes maximum @ 250V AC or 30V DC.
Operating Temp. Range:-40 C to 65 C. Mounting:Single center hole mount.Timing cycle interrupt
transfer: None.
Ordering Information:
Refer to model chart below. Select appropriate model number in accordance with the power input and load current required, and
specify desired flash rate in flashes per minute (FPM). Standard flash rates:30, 45, 60, 75, 90 and 120 FPM.
Note: Custom voltages and flash rates are available;consult factory.
