Electrical feature specifications of the ALMO1 and ALMO2 interfaces

Output and cascading interfaces (ALMO1 and ALMO2) generally transmit housekeeping alarm outputs to a PDF to display alarm information in a centralized manner. The interfaces can also be configured for other outputs. Alarm signals are output based on the open/closed status of the relay on the related board. When the relay is open, the resistance measured at the ALMO interface is less than 1 ohm. When the relay is closed, the resistance is infinite.
