ESDR Series Information

  • ON/OFF Recycling with Independent‑Adjustment of both the On and Off Periods
  • Factory Fixed, Onboard or External Adjust
  • 0.1s to 1000m in 6 Ranges
  • ±0.1% Repeat Accuracy
  • ±5% Factory Calibration
The ESDR Series offers independent time adjustment of both delay periods. Adjustment options include fixed, onboard or external adjust. The ESDR is recommended for air drying, automatic oiling, life testing, chemical metering and automatic duty cycling. This series is designed for general purpose commercial and industrial applications where a small, cost effective, reliable, solid‑state timer is required. The factory calibration for fixed time delays is <±5%. The repeat accuracy, under stable conditions, is 0.1% of the selected time delay. This series is designed for input voltages of 12VDC to 230VAC in five ranges. Time delays of 0.1 seconds to 1000 minutes are available in six ranges. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry.

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 first delay.

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 first delay.

  • Available in AC or DC Voltages
