Determination of the signal level for a voltage connected to an input AC/DC 10…230 V

At every input, it is possible to connect any phase L1, L2 or L3 or a FELV signal.

It is possible to use different FI on the inputs.

Signal level Uin < x V, logically corresponds to 0

5 V

Signal level Uin > x V, logically corresponds to 1
