The module contains a source which can be used to connect the digital inputs. When using the
power down function it’s highly recommended to use this source over the input voltage to connect
the digital inputs. Otherwise the change of the digital inputs could be detected before the power
down, causing the module to send digital input change messages and not having enough capacity to
also send the power down message.
NOTE: the V+ is a source with 20mA which is designed for signalling. This connection is not suitable
as power supply.
