IDEC GT3F-2AD24 True Off Delay Relay 24VAC/DC DPDT 600SEC, 8 Pin Timer, 3A@250VAC/30VDC (Resistive Load)

True off delay relay, 0.05-600 seconds (multiple ranges available)
Function starts when power is removed from relay coil.

Input coil : 24v ac or dc
Contacts : DPDT
Time ranges : 0.05s to 1s, 0.05 to 3s, 0.05 to 6s, 0,1s to 10s, 0.3s to 30s, 0.6s to 60s,1.8s to 180s and 6s to 600s

True off delay function
Upon application of input voltage (coil), the output is energized. When the input voltage is removed, the timing function begins. At the end of the timing cycle, the output is de-energized. Input voltage must be applied for a minimum of 0.4 seconds to assure proper operation. Any application of the input voltage during the time delay will reset the time delay. No external trigger switch/circuit is required.
