6.4.13 TERMINALS A1-A2: ISOLATED ANALOG OUTPUT – TYPE AH
The flowrate proportional output (AH) is standard available. This output is an isolated 4-20 mA
output with the possibility to power the device via the 4-20 mA loop. It is non-polarity sensitive.
When the output is disabled, the current is by default limited to 2 mA. Max. driving capacity
1000 Ohm @ 27 VDC. If only powered by the loop, the backlight will not be activated.
The total loop resistance may not exceed 1000 Ohm and may not be less than 330 Ohm (at 30 mA).
This means that the total resistance of other loop-devices may not exceed 670 Ohm.
