AI summary

Method for configuring a two-pole electrical input (100) equipped with means for measuring electrical voltage, electrical current, and/or electrical resistance, and with a controller (140). After an electrical input signal (In) is applied to the two-pole electrical input (100), the controller (140) determines, by means of at least one measurement, whether the input signal (In) originates from an electrical voltage source, an electrical current source, an electrical resistance, or an electrical switch, and then adapts the input (100) to the determined source of the input signal (In). The input signal (In) is thus uniquely identified. The input (100) is therefore able to adapt itself to input signals (In) and to recognize connected devices. This makes the configuration of two-pole inputs (100) both simpler and safer.The same applies to the installation, maintenance and operation of (field) equipment and systems.
