All 16 inputs are suitable for standard sensors of the types KTY (2 kΩ) and PT1000 or for
digital inputs. In addition, the following inputs have special functions:
| Inputs | Description |
|---|---|
| S8: | Current loop (4 – 20 mA) or control voltage (0 - 10V=) |
| S15, S16: | Pulse input, such as for volume flow encoder |
Signal voltages of more than 5 V at the inputs S1 to S7 and S9 to S16 or more than 10 V at S8 are not allowed.
