Connection Example 1:
This is the most inexpensive way for fully autonomous DO control. To be sure that the control is working properly, one can check the sensor status and the current measured values via the Sentro.IO from the aDO sensor with the Sentro.IO TAGs/Mobile app. As a result, no PLC/DCS or display is needed but can be connected to the RS485 if required.

Connection Example 2:
This is also an inexpensive way for fully autonomous DO control with the possibility to control 2 actuators (e.g. solenoid valves). To be sure that the control is working properly, the sensor status and the current measured values via the Sentro.IO from the aDO sensor can be checked with the Sentro.IO TAGs/Mobile app. As a result, no PLC/DCS or display is needed, but can be connected to the RS485 if required.

Connection Example 3:
This is also the most inexpensive way for fully autonomous DO control with the possibility to indicate directly an alarm. To be sure that the control is working properly, one can check the sensor status and the current measured values via the Sentro.IO from the aDO sensor with the Sentro.IO TAGs/Mobile app. As a reuslt, no PLC/DCS or display is needed, but can be connected to the RS485 if required.

Connection Example 4:
You can directly control the locally connected hardware, e.g. by your PLC/DCS. If this control is not longer available, e.g. due to a cable break, the local hardware-control-unit of the aDO-Sensor takes over this task until an external control is available again. In addition, the optional software control unit can be used to control other actuators connected to the PLC, for example. By using validated software control functions of the aDO sensor, programming and testing efforts can be saved.
