ERDI Series Information

  • Factory Fixed, Onboard or External Adjust
  • Delays from 0.1s‑1000m in 11 Ranges
  • ±0.5% Repeat Accuracy
  • ±10% Factory Calibration
  • Encapsulated Digital Circuitry
Econo‑Timers are a combination of digital electronics and an electromechanical relay. DPDT relay output for relay logic circuits, and isolation of input to output voltages. For applications, such as interval on, pulse shaping, minimum run time, etc. The ERD Series is encapsulated to protect the circuitry from shock, vibration and humidity.

Operation (Interval): Upon application of input voltage, time delay begins, and output relay energizes. At the end of time delay, output de‑energizes until input voltage is removed. Reset: Removing input voltage resets the time delay and the output.

Operation (Single Shot): Input voltage must be applied before & during timing. Upon momentary or maintained closure of initiate switch, output relay energizes for time delay. At the end of the delay, output de‑energizes. Opening or reclosing initiate switch during timing has no affect on time delay. Output will energize if initiate switch is closed when input voltage is applied. Reset: Reset occurs when time delay is complete & initiate switch is opened. Loss of input voltage resets time delay & output.

  • Isolated, 10A, DPDT Output Contacts
