ANB Sensors DTU-A Analogue Signal Unit
Part no.: DTU-A
Surface converter that gives a 4 to 20 mA or 0 to 5 V signal from an AQ2 sensor and also links to a PC over USB like a DTU.
- 4 to 20 mA or 0 to 5 V output
- Scaled pH 2 to 10
- Test mode to verify the signal
- Also works as a DTU over USB
- For installation on the surface

The DTU-A is a converter for installation on the surface. It turns the AQ2 sensor's digital output into a 4 to 20 mA current or 0 to 5 V voltage signal, so the sensor connects to loggers, PLCs and legacy systems that need analogue inputs. It also does the job of a DTU and links to a PC over USB.
The signal spans pH 2 to 10. A test mode steps the output through 0, 25, 50, 75 and 100 percent so you can confirm the receiving system reads correctly, for example 8 mA or 1.25 V at 25 percent.
Wiring is through a 6-pin DIN connector. The current loop takes 12 to 24 V, and ANB recommends a splice kit when connecting the DTU-A to a pigtailed sensor.
