- the external DC voltage source 20 is connected to the input connections 30 and 31, which supplies a DC voltage of 24 V, for example, and the switch 21 is closed. After the switch 21 is closed, the current in the current measuring path 50 caused by the input control voltage is measured by the current sensor 52.
- the electrical resistor 51 in series with the current sensor 57 which is preferably low-resistance and whose value is known, is preferably used to set a base load current through the current path 50 in order to be able to minimize susceptibility to interference from external influences.
- the resistance value of the resistor 51 is stored, for example, in the memory 95 and is thus known to the microcontroller 70 or the microprocessor 76, together with the three reference values of 24V, 48V and 60V.
- the analog value measured by the current sensor 52 is fed to the A/D converter 79 of the microcontroller 70 via the analog input 72.
- the microprocessor 76 of the microcontroller 70 is programmed in such a way that it determines a voltage value depending on the digital current measurement value received via the A/D converter 79 and the known resistance value of the electrical resistor 51.
- the microcontroller 70 or the microprocessor 76 can preferably be designed to check whether the determined voltage value can be assigned to one of the reference values stored in the memory 95. In the present case, the microprocessor 76 recognizes that the determined voltage value can be assigned to the reference value 24V.

In other words: after completion of the initial commissioning, the switching device 10 has automatically configured itself with regard to the input control voltage applied to the input terminals 30 and 31.
- the current sensor 52 expediently continuously measures the current through the current measuring path 50 and transmits the current measurement values to the microcontroller 70 at regular intervals, preferably almost continuously.
- the microcontroller 70 determines that the direct current voltage of 24V applied to the input terminals 30 and 31 is applied continuously for a defined period of time - i.e. the microprocessor 76 determines a voltage value during this period that is greater than or equal to the switch-on voltage threshold value stored in the memory 95 - the microcontroller 70 or the microprocessor 76 applies an activation signal to the digital output 75, which ensures that the switching element 110 is closed. Consequently, the output voltage of, for example, 12V applied to the output 64 of the direct current converter 61 is fed to the electromechanical switch 100 or the excitation coil 101, so that the switching element 102 of the electromechanical switch 100 is switched accordingly.
- a current-carrying excitation coil 101 ensures that the switch 102 closes a load circuit at the terminals 120 and 121.
- the microcontroller 70 is designed to transmit a corresponding control signal, for example a binary coded 1, to the optical and/or acoustic output device 80 via the output 74 after initial commissioning.
- the optical and/or acoustic Output device 80 is designed to evaluate the binary coded 1 and to output the number 1, for example, by means of a single flashing pulse and/or a corresponding voice utterance by an operator.
- the number 1 output in this way signals to an operator that the switching device 10 is currently being operated with an input control voltage of 24V.
- the electromechanical switch 100 remains in switching state 1, i.e. current flows through the excitation coil 101, until the input control voltage at the input terminals 30 and 31 falls below the switch-off voltage threshold value stored in the memory 95.
- the microcontroller 70 recognizes this because the current continuously measured by the current sensor 52 through the current path 50 drops, so that the microprocessor 76 determines a voltage value that is below the switch-off voltage threshold value stored in the memory 95.
- the microprocessor 76 applies a deactivation signal to the digital output 75.
- the switching element 110 is opened.
- the excitation coil 101 no longer carries current and the electromechanical switch 100 goes into a second switching state in which a second load circuit (not shown), which is connected to the terminals 121 and 122, is now closed via the switch 102, while the first load circuit (not shown) is opened.
- an operator can apply a first control signal to the input 32 of the switching device 10 in order to be informed of the current configuration, i.e. the input control voltage currently used by the switching device 10.
- the microcontroller 70 is designed to evaluate a corresponding control signal arriving at the input 73 and to transmit a corresponding control signal, in the present embodiment a binary coded 1, to the optical and/or acoustic output device 80 via the output 74.
- the optical and/or acoustic output device 80 is designed to evaluate the binary coded 1 and to output the number 1, for example by means of a single flashing pulse and/or a corresponding voice utterance by an operator.
- the control signal output in this way Number 1 signals to an operator that the switching device 10 is currently operated with an input control voltage of 24V.
- an operator can apply a second control signal, a so-called reset signal, to the input 73 of the microcontroller 70.
- a second control signal a so-called reset signal
- the microcontroller 70 or the microprocessor 76 is designed to delete the switch-on and switch-off voltage threshold values currently stored in the memory 95 in response to a reset signal.
- an input control voltage for example an input control voltage of 48V
- the configuration procedure previously described with regard to the initial commissioning is carried out again, so that at the end of a proper configuration phase, the switch-on and switch-off voltage threshold values associated with the reference value of 48V are read out from the memory 90 by the microcontroller 70 and stored in the memory 95 as the current switch-on and switch-off voltage threshold values.
- the exemplary switching device 10 can also be operated in a so-called self-learning mode in which the switching device 10 automatically reconfigures itself, i.e. adjusts itself to a new input control voltage value and to the associated switch-on and switch-off voltage thresholds.
- the switching device 10 is configured according to the initial commissioning described above to an input control voltage value of 24 V and the associated switch-on and switch-off voltage threshold values, which are stored in the memory 95.
- the sensor 52 is designed to continuously measure the current through the current path 50 during an input control voltage applied to the input terminals 30 and 31, the measured current value being fed to the microprocessor 76 of the microcontroller 70 via the A/D converter 79.
- the microcontroller 70 or the microprocessor 76 is designed to periodically, or almost continuously, determine the to determine a voltage value from the measured current values arriving at input 72 and to check whether the determined voltage value can be assigned to one of the three stored reference values, i.e. 24V, 48V and 60V.
- the changed input control voltage in this case the new input control voltage 48V
- the current sensor 52 measures a correspondingly increased current value for the predetermined period of time, which is fed to the microprocessor 76 via the input 72 and the A/D converter 79.
- the microprocessor 76 determines voltage values during the predefined period of time and determines that the determined voltage values can all be assigned to the reference value of 48V stored in the memory 95 during the predetermined period of time.
- the microprocessor 76 requests the memory device 90 via the connection 77 to send the switch-on and switch-off voltage threshold values associated with the reference value of 48V.
- the microcontroller 70 or the microprocessor 76 is programmed to delete the turn-on and turn-off voltage threshold values associated with the old input control voltage of 24 V and replace them with the new turn-on and turn-off voltage threshold values, or to overwrite the old turn-on and turn-off voltage threshold values in the memory 95 with the new received turn-on and turn-off voltage threshold values associated with the input control voltage of 48 V.
- the exemplary switching device 10 is thus capable of self-learning, ie automatically recognizing whether a new input control voltage has been applied to the input terminals 30 and 31 during ongoing operation. In response to this, the switching device 10 configures itself, ie the Microcontroller 70 ensures that the turn-on and turn-off voltage thresholds associated with the new input control voltage of 48 V are now activated by writing them into memory 95. This means that when the current input control voltage of 48 V applied to input terminals 30 and 31 falls below its associated turn-off voltage threshold, microcontroller 70 detects this and then opens switching element 110.
- the microcontroller 70' is implemented in the switching device 10 instead of the microcontroller 70 and/or the optocoupler 100' is implemented in the switching device 10 instead of the electromechanical relay 100.
