Interface specifications

2.5.1.

Analogue inputs

8x 4-20 mA standardised signals can be connected to the analogue inputs.
The potential difference of the signal terminals to the device earth must not
exceed 20 V.
The I/O board provides a maximum of 24 V max. 1 for passive water level
sensors.
The I/O board's inputs and outputs can be switched actively or passively
with microswitches (see the chapter 4.5).
Input signals smaller than the start of the measurement range and larger
than 21mA are evaluated as defective.
2.5.2.

Analogue outputs

The assigned variable is represented by a 4 -20 mA standard signal at the
active analogue outputs. The output can be assigned to the outflow, the
mean flow rate, the water temperature or various variables dependent on it.
The measuring ranges can be freely configured by entering the full
measuring scale.
If a variable is evaluated as defective, the analogue signal is reset to <3.6
mA. For values outside of the full measuring scale, the output takes the
relevant extreme value (3.84 or 20.5mA).
