The potential divider with manual control level is used and 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.
Supply voltage 24 V AC/DC
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.
This are the differences between the PT-C12 and the PTi-C12:
| Input | Output | PT-C12 | PTi-C12 |
| 0 bis 20 mA | 0 bis 10V DC |  | |
| 0 bis 10 V DC | 0 bis 20 mA | | |
| 0 bis 20 mA | 0 bis 20 mA |  | |
| 0 bis 10V DC | 0 bis 10V DC | | |
