The potential divider is used for dividing analog signals in a range from 0 to 10 V DC or 0 to 20 mA. The input and output signals and the supply are mutually isolated. An input signal (0 to 10 V DC or 0 to 20 mA) can be applied optionally to the potential divider. Independently of the type of signal on the input, a voltage of 0 to 10 V DC or a current of 0 to 20 mA can be measured on the output proportionally to the input signal. In addition, a manual emergency operation level with checkback is integrated. A fix 10 V DC signal can be scanned for anti-frost or similar equipment. An external signal (0 to 10 V DC) can be applied to the LED control input Y. Without external signal, the proportional output signal can be indicated by means of the integrated LED by connecting a bridge between Ua and Y. If a voltage signal is used on input and output, use PT-C12. If a current signal is used on input and output, use PTi-C12.
