5 Hardware Interface
5.1.3 Trigger and Strobe Signals
The power connector contains an external trigger input and a strobe output.
The input voltage to the
TRIGGER
pin must not 15V DC, to avoid damage
to the internal optocoupler!
In order to use the strobe output, the internal optocoupler must be powered with 5 .. 15 V DC.
The
STROBE
signal is an open-collector output, therefore, the user must connect a pull-up
resistor (see Table 5.1) to
STROBE_VDD
(5 .. 15 V DC) as shown in Fig. 5.2. This resistor should be
located directly at the signal receiver.
Figure 5.2: Circuit for the trigger input and strobe output signals
The maximum sink current of the
STROBE
pin is 8 mA. Do not connect inductive
or capacitive loads , such loads may result in damage of the optocoupler! If the
application requires this, please use voltage suppressor diodes in parallel with
this components to protect the opto coupler.
The recommended sink current of the TRIGGER pin is 5 mA.
