BCS-HOA-3-BACNET | Schneider Electric | Control Valves & Actuators

DESCRIPTION The Three Channel HOA BACnet Digital Out Override Cards allow for manual override switching of a controller's output channel. These cards were designed for the TAC MNB-300 and MNB-1000 Controllers but may be applied to any controller via interposing terminals. The HOA BACnet card 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 INX and COM provide an individual switch status. The same circuitry used in the DPC-3-1 has been used on these cards to provide status back to the controller when any one or more switches are out of the Auto position.
