What is the new option for the old 873-AC board?

When the new PS900 series power supplies were created we did not pursue a version of these option boards.  Need to discuss the specific hardware they are using and requirements to determine the appropriate hardware.

  • 873-AC (access control) and 873-AL (alarm) boards were the option boards for PS873 power supply.
  • There are no replacement for 873-AC and 873-AL option boards when ordering a new PS900 series power supplies.
  • The 873-AC and 873-AL boards were used for Access Control systems and alarm output openings and they were not commonly sold.
