A RelayOutputWritable is a BooleanWritable with NrioRelayOutputProxyExt. It represents a digital output (DO) as a relay type output. All standard BooleanWritable features apply, including right-click actions, priority input scheme, and minimum on/off properties (for details, see “About writable points” in the User Guide).

The default operation is normal logic (closed contacts at DO if input value “true”). If needed, you can “flip” this logic in the ProxyExt by assigning a Conversion type of “Reverse Polarity.” This causes the “reversed” boolean state going from input to output.

The RelayOutputWritable has the common Nrio Proxy Ext properties.
