Interval Timer
Product Status| Activei
info
The ERD Series is 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.

  • Digital integrated circuitry
  • Isolated, 10A, DPDT output contacts
  • Encapsulated
  • Repeat Accuracy + / - 0.5%, Factory calibration +/ - 10%
  • Allows control of loads for AC or DC voltages
  • Protects against shock, vibration, and humidity
