Thanks to their modular design MAC units can be configured for small and large sites.
Multiple Input/Output configurations allow you to choose the appropriate size of MAC unit. Expansion can be achieved by networking up to 4 MAC units through Ethernet connections.

| Virtual Logic Gates | 128 | Program conditional actions and complex logic functions, to control relays, set qualifiers, view flags or other events. In addition, MAC units have qualifier and inverter functions on all inputs. |
| Virtual Relays | 128 | Use the latch and pulse functionalities to qualify conditional actions without using physical relays. |
| Timers | 128 | Set date/time events & windows. For example, AM antenna pattern changes with specific time windows for each month. |
