Discrete outputs (OUT-3) allow handling extra equipment. When switched on, a discrete
output is connected to the minus of the tracker external power supply, and the connection should
be performed according to the layout.
It is allowed to connect devices with the maximum current consumption not exceeding 100mA,
otherwise there is a risk to damage the tracker. When a more powerful load commutation is
needed, it is necessary to use a relay.
To prevent the tracker exposure to self-induction pulses, which appear after switching off the
inductive load (including the relay coil), it is necessary to connect a diode in parallel to the relay
coil in the opposite direction. A layout for connecting relay to the tracker discrete output is
provided in the Figure 9. A layout for connecting buzzer and LED to the tracker discrete output is
provided in the Figure 10.
It is possible to control the output condition with the
«
OUTPUT X,Y»
command.
X=0...3
– discrete output number
Y=1
– switch on (close the output to ground),
Y=0
– switch off (open the output to ground).
The response to the
«OUTPUT»
command always displays the condition of four outputs:
OUTPUT (3..0) = 0000. It is possible to make the output condition dependent on an event at the
analogue input via
«INTRUEOUT»
command.
