1. Control mode: It can be set to proportional modulating mode or on/off mode.
Proportional modulating mode: Input the controlling signal 4-20mA or 0-10mA DC. The voltage signal 0-5V or 1-5V.

Output signal of position feedback 4-20mA or 0-5V DC, the input impendence:1)the current model 250Ω. 2) the voltage model 100 kΩ.

The on-off model: The input is the passive on-off signal. It can be used as the remote model and the on-off model.

2. The mode of the output shaft: It can be set at the position action or the reversed action.  Meanwhile, the input and the output signals are changed automatically with action direction.

3. Deadline: 0.3-3% arbitrary

4. The upper and downer position limit modes:

1) The soft position limit setting: the downer limit can be set at 0-99%, the upper limit can be set at 1-100%

2) The up and down travel position limit.

5. Basic error: ± l%;
6. Power supply: 220V ± l0% 50HZ; 380V ± 10% 50HZ
