4.5.3 Relay Connection
The GAT NET.Controller M 7020 has four potential-free relay outputs (1 in Figure 4.15) that can be used to send
signals when a certain event occurs. The master controller also has four optocoupler inputs (2 in Figure 4.15) that
are currently reserved for future use.
The GAT NET.Controller M 7020 Light is intended for smaller systems and has no inputs and outputs.

Some application examples for the relay outputs include:
- To trigger an alarm notification system. If a break-in is attempted at a locker, an alarm is triggered in GAT
Relaxx. An additional alarm notification system with flashing light and beeper can be installed in a visible
position to immediately alert staff of the security problem.
- To trigger a locker occupancy system. The relay could be configured to indicate, e.g., via a display installed
above the locker room entrance, when the controlled lockers are almost fully occupied.
