Field Wiring
4.5 Digital Relay Outputs
Outputs 1 and 5 have common (labeled BO ), normally open (labeled no ), and normally closed
(labeled nc ) contacts.
Outputs 2-4 and 6-8 have 2 contacts and can be configured in the software as normally open
or normally closed. By default they are normally open.

damper with 1-10 VDC
control input
Attention: If DC voltage with anything other than purely resistive load is used on
the digital outputs, then the appropriate protective devices must be
installed.
