The TDR2A23 is a recycling time-delay relay with a 10A electromechanical relay output for 24VAC input and ON-time-first sequencing. Its ON time is adjustable from 1 to 1023 seconds in 1-second increments, and its OFF time from 10 to 10230 seconds in 10-second increments. It uses an 8-pin plug-in package measuring 81.3 mm × 60.7 mm × 45.2 mm. A green LED indicates input voltage presence; a red LED shows relay energization. The relay has 10A resistive ratings at 240VAC, 250VAC maximum switching voltage, and ±0.1% or 20 ms repeat accuracy. Reset time is ≤50 ms, and recycle time is ≤150 ms. Isolation voltage is ≥1500V RMS, and operating temperature ranges from -20°C to 65°C.
The TDR Series of time-delay relays are comprised of digital circuitry and an isolated, 10A relay output. The on and off delays are selected by means of two, ten position binary switches, which allow the setting of the desired delay to be precise every time. Operation (Recycling - ON Time First)Upon application of input voltage, the green LED glows, the output relay is energized, the red LED glows, and the T1 ON time begins. At the end of the ON time, the output deenergizes, the red LED turns OFF and the T2, OFF time begins. At the end of the OFF time, the output relay energizes and the cycle repeats as long as input voltage is applied.Reset: Removing input voltage resets the output and time delays, and returns the sequence to the first delay. Operation (Recycling - OFF Time First)Upon application of input voltage, the green LED glows, the T1 OFF time begins, the load is OFF. At the end of the OFF time, the T2 ON time begins, the load energizes, and the red LED glows. At the end of the ON time the load de-energizes and the red LED turns OFF. The cycle repeats until input voltage is removed.Reset: Removing input voltage resets the output and the sequence to the OFF time.
