3.7.7 Outputs
CAUTION: When Outputs 1 and 2 are connected through the TCNM-ACBB1 connection box, they
become opto-isolated and polarity sensitive and acquire the electrical characteristics listed below. To
function correctly, they require setting the Output Line Type configuration parameters to NPN for the
respective output. The hardware connection to the TCNM-ACBB1 can be either NPN or PNP.
Two general purpose outputs are available and their meaning can be defined by the user. They are typically used either to
signal the data collection result or to control an external lighting system.
The third output of an ABR 7000 is not accessible when using a TCNM-ACBB1 connection box.
