2.3.1. Digital Output
The digital output is implemented in the form of NPN with an open collector(OC).
When the digital output is activated, the corresponding connector will be driven to
GND. When the digital output is disabled, the corresponding connector will be open
(open collector/open drain). The electrical specifications are as follows:

2.3.1.1. Tool Digital Output Usage
The following example illustrates how to use the digital output. As the internal output
is an open collector, the resistor should be connected to the power supply according to
the load. The size and power of the resistor depend on the specific use.
Note: It is highly recommended to use a protection diode for inductive loads as shown
below.
There is no current protection on the digital output of the tool,
which can cause permanent damage if the specified value
exceeded.
