Electronic Timer Relays Perform in Universal Applications
Phoenix Contact introduced its family of electronic timer relays (ETDs) that offer a range of timing settings and other practical functions. Featuring easy set-up and diagnostics, the ETDs are appropriate for use in universal applications. They monitor different time functions without using complicated controllers. The timer relays can be adjusted to an array of timing settings ranging from milliseconds through several days. ETD devices equipped with special functions, including star/delta (or Wye/Delta) and watchdog, are also available. To set up the timer relays, the potentiometers on the top of each module set the appropriate limit values. Colored LEDs report the operating statuses such as “power supply OK” as well as limit value and relay state.
