RS Series Information

  • Accurate, Reliable, Recycling Timer
  • Switch Settable Time Delays‑Both Times Adjustable
  • ±0.1% Repeat Accuracy
  • ±2% Setting Accuracy
  • 0.1s‑102h in 4 Ranges
The RS Series is a solid‑state, encapsulated, recycling timer designed for tough industrial environments. It is used by many testing labs as a life cycle tester; by others as a cycle controller. The RS Series has separate DIP switch adjustments for the on delay and the off delay. These make accurate adjustment possible the first time, every time. Time delays of 0.1 seconds to 1023 hours are available in 4 ranges.

Operation (Recycling ‑ ON Time First) Upon application of input voltage, the output energizes and the T1 ON time begins. At the end of the ON time, the output de‑energizes and the T2 OFF time begins. At the end of the OFF time, the output 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 ON time.

Operation (Recycling ‑ OFF Time First) Upon application of input voltage, the T2 OFF time begins. At the end of the OFF time, the output energizes and the T1 ON time begins. At the end of the ON time, the output de‑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 OFF time.

  • 12 to 230V in 5 Options
  • 1A, Solid‑State Output
