5.7.2 Digital Inputs
The TV30 SA camera provides 3 digital inputs which can be used as switch to initiate different tasks, see section
7.4.1
<I/O>
<Internal>, page 48.
A high signal requires voltages of 4.5 - 24 V. A low signal is detected for voltages below 2 V.
The digital inputs are galvanically isolated from GND power and housing ground but not from each other
5.7.3 Digital Outputs
The TV30 SA camera provides 3 digital outputs which can be used to indicate different tasks, see section
7.4.1
<I/O>
<Internal>, page 48.
The signal output can be done in a specific mode. The desired mode can be set via the user and always applies
to all outputs. The following modes are available:
Pull-Up – the pull-up resistor is provided internally. The logical high level is fixed to +5 VDC.
Open-Drain – requires the provision of an external pull-up resistor and a voltage supply. The logical high
level is determined by the external voltage supply and not limited to +5 VDC.
