The DCM and the related Function Modules (FM) were installed in the Base-Frame configuration of the earliest generation of the Metasys system. These devices can be found managing central plants, air handling units, and a wide variety of other applications.

  • FEC controllers and the CGM09090 can be used to replace these controllers:
    • DCM101 (10 inputs,10 outputs, 16 PID Loops)
    • DCM140 (20 inputs, 20 outputs, 20 PID Loops)
  • The replacement controller varies. The selection is based on systems managed through DCM I/O points.
  • FMs with pneumatic outputs need to be replaced by ancillary devices, that use AO or CO outputs.
