Recycling (Flasher)
ERD3 Econo-Timer
Time Delay Relay
Description
Econo-Timers are a combination of digital electronics and a reliable electromechanical relay. DPDT relay
output for relay logic circuits, and isolation of input to output voltages. Cost effective for OEM applications such
as duty cycling, drying, washing, signaling, and flashing.

Function
Upon application of input voltage, the output energizes
and the ON time begins. At the end of the ON time, the
output de-energizes and the OFF time begins. At the
end of the OFF time, the output energizes and the
cycle repeats as long as input voltage is applied. The
OFF time may be the first delay in some recycling
timers.
Reset: Removing input voltage resets the output
and time delays, and returns the sequence to the first
delay.
