Select the relay source (a digital source) to be used to
energize/de-energize the relay.
Note. If the relay is used to provide a totalizer count pulse,
the maximum pulse frequency is 5Hz. Consideration must
also be given to the mechanical life of the relay.
Select the relay source polarity.
Note. When polarity is set to 'Positive', the relay is
energized when the digital source is active (On).
