Installation of the digital output
According to the E1 certificate of the ME401-9 unit, it is prohibited under any
circumstances to use this output to control any equipment that may influence the safety of
the construction machinery and earth moving machines/vehicle operation and driving. The
output must only be used to control comfort equipment.
The example below shows a relay function. Please ensure that the voltage specification of
the relay matches the supply voltage. The current consumption of the relay must not
exceed 200 mA (DC current) and the relay contacts must be specified to withstand the
load that needs to be controlled.
NOTE:
the relay matches the supply voltage. The current consumption of the relay must not
exceed 200 mA (DC current) and the relay contacts must be specified to withstand the
load that needs to be controlled.
NOTE:
The output can only handle DC and
not AC voltage. It is necessary to only use a
DC power supply for the relay.
Important!
The power supply connected to the ME401-9 GSM/GPS unit and
the supply voltage for the relay mounted on the digital output
must have a common ground connection.

must have a common ground connection.
One application example for the “Usable contact function controlled by the ME401-9”
signals shown in the figure above could be a “Start Relay”, blocking function, for
preventing unauthorized use of the moving machinery and construction machine or vehicle
outside normal working hours etc.
