Metz Connect PT-F-C12

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 from 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. The device can be connected to either an input signal of 0 to 10 V or 0 to 20 mA.

Function of potential isolation: In the PT-C12, the input signal of 0 to 10 V is proportionally matched to the output signal of 0 to 10 V. The PTi-C12 matches the input signal of 0 to 20 mA proportionally to the output signal of 0 to 20 mA.

Function of signal conversion with potential isolation: When converting a signal from 0 to 10 V to 0 to 20 mA or from 0 to 20 mA to 0 to 10 V, the converted output signal can be fine-tuned using an integrated spindle trimmer. Additionally, a manual emergency operation level with a HAND-AUTO switch and feedback contact is integrated. Using the front-mounted potentiometer, the output signal can be set to 0 to 10 V or 0 to 20 mA in the HAND switch position. A constant output voltage of up to 10 V DC, 5 mA is available at the 10 V terminal. The input Y is used for the LED display of the output voltage Ua. The brightness of the LED depends on the level of the output signal (bridge between Ua and Y). Alternatively, an external signal can be connected to input Y for the LED display of 0 to 10 V DC. Connection is made with spring-loaded terminals (Push-In).
