The potential isolator/signal converter is used to separate analog signals in the range of 0 to 10 V DC and 0 to 20 mA DC or to convert signals from 0 to 10 V DC to 0 to 20 mA DC or 0 to 20 mA DC to 0 to 10 V DC. The input and output signals as well as the supply voltage are mutually isolated. Either an input signal of 0 to 10 V or 0 to 20 mA can be connected to the device. Potential separation function: With the PT-C12 230, the input signal 0 to 10 V is proportionally adjusted to the output signal 0 to 10 V. The PTi-C12 230 adjusts the input signal 0 to 20 mA proportionally to the output signal 0 to 20 mA. Function Signal conversion with potential separation: When converting a signal from 0 to 10 V to 0 to 20 mA or 0 to 20 mA to 0 to 10 V, the converted output signal can be readjusted using the integrated spindle trimmer. In addition, a manual emergency operating level with HAND-AUTO switch with feedback contact is integrated. The output signal 0 to 10 V or 0 to 20 mA can be set using the front-side potentiometer in the HAND switch position. A constant output voltage of max. 10 V DC, 5 mA is available at the 10 V terminal. The integrated LED is used to display the brightness depending on the level of the output signal Ua. Connection with screw terminals
