A new family of electronic timer relays (ETDs) monitor different time functions without using complicated controllers.
Adjustable timing settings range from milliseconds through several days. ETD devices equipped with special functions, including star/delta (or Wye/Delta) and watchdog, are also available. Appropriate limit values are set using the potentiometers on top of each module and colored LEDs report operating status.
