4 Channel Digital Override Card to allow Switching of a Controller's Output Channel.

The HOA-4 Digital Out Override card has four channels. These cards allow for manual override switching of a controller's output channel. The card was designed for the Barber Colman Network 8000 Microzone II Controller but may be applied to any controller via interposing terminals. The HOA-4 allows an operator to manually select On-Off-Auto positions for a particular piece of equipment. Monitoring of its own override status is an added feature. Terminals OVR and OVR provide a normally closed contact which opens when any switch is placed out of the Auto position.
