    Built-in Digital Timer
    The RFD-200 S3’s digital timer features independent start and stop trigger inputs designed to measure the time between event transitions and to display the elapsed time in both milli-seconds and cycles.

    The RFD-200 S3’s timer has three different trigger inputs – Internal Trigger, Dry-Contact, or Wet-Contact. The Internal Trigger can start or stop the timer by sensing the application or removal of the unit’s voltage or current source.


    The Dry-Contact can trigger the timer by detecting a change in state of the dry-contact input. Similarly, the Wet-Contact can trigger the timer by detecting a change in state of the voltage input. Thus, the three inputs can trigger the timer by the presence or removal of the unit’s voltage or current source or by changes in voltage or current states.

     

    AC Current Source
    An AC current source with three outputs (10A, 40A, and 100A) provides test current to relays.

    The current source output can be programmed to synchronize with the RFD-200 S3’s timer.

    After a test is completed, the test current reading is latched and displayed on the LCD screen.

    This feature reduces the possibility of overheating the relay coils.

     

    AC Voltage Source
    An AC voltage source is available for testing relays up to 250 Vac. The AC voltage source output
    can be programmed to synchronize with the RFD 200 S3’s timer.
