TTL switching output

The switching output serves for external control pur- poses if there is a gate alarm. According to the follow- ing table, the following voltages are available at the connections 5 (green) and 6 (ground, blue):

 

GATE LOGIC: POSITIVE

GATE LOGIC: NEGATIVE

 

 

 

Echo < gate threshold

0 volt

5 volts

 

 

 

Echo > gate threshold

5 volts

0 volt

 

 

 

The maximum load capability of the switching output is 2.5 mA.
