The base model of HCC is supplied with an ICM-800 station output module. The capacity of the controller is increased when new station modules are installed and recognized.
Standard ICM station modules are available in 4, 8, and 22 station sizes (ICM-400, ICM-800, ICM-2200). These may be added at any time after initial installation.
Note: The ICM-2200 (22 Station module) should always be installed in the last two module slots to make it compatible.
