The RFD-200 Digital Timer can be started or stopped in three different modes:

  1. Internal Trigger: Start timer with the presence or removal of RFD-200 voltage or current source.
  2. Dry Contact: Change of state of a dry contact input.
  3. Wet Contact: Change of state of a DC voltage input.
Specifications are valid at nominal voltage and ambient temperature of +25˚C (+77˚F).
