SSAC

Timing Relays, TDR Series

Item# TDR4A12 - Time Delay Relay, Recycler, 120VAC On time First, 0.1-102.3/1-1023 Sec DIP Switch Selectable, DPDT 10A Out

TDR Series Information
  • Switch Settable Time Delays ‑ Both Times Adjustable
  • 0.1s-2.84h in 3 Ranges
  • ±0.1% Repeat Accuracy
  • ±2% Setting Accuracy
  • Isolated, 10A, DPDT Output Contacts
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 de‑energizes, 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.

  • Octal Plug-in Base Connection
