Terminal 1, 2:
A two-pin, bi-directional LED (red/green) can be connected. The LED shows the same status
as the LED of the external antenna and the DFT after a proper connection.
Terminal 6+7, 8+9:
Two signal inputs can be used as current-controlled inputs (optocoupler inputs). An internal power
source for controlling these inputs is available. They are controlled via potential free contacts.
The inputs can be queried via
Terminal 10, 11, 12:
The DFT has a relay output (NO, NC and COM). This relay is controlled by
Terminal 13:
The voltage at terminal 13 can be switched to the consumer to be switched for a direct control
of small consumers (such as piezo sound generators or other signal generators).
Macros are programmes that expand the functionality of the DFT. It controls the relay (10, 11, 12)
in reference to the input signals (6,7,8,9). Contact the manufacturer for the development of the
macros.
