When the device is powered, the led will be on.

- mA (negative, passive output)
The analog output is a current loop working linearly between 4 and 20 mA and proportional
to flow rate. When the converter detects empty pipe, the current loop gives a value of 3.6
mA, and when the flow rate is negative and the current output is configured as
unidirectional (see point 7.5.1), the loop will give 21 mA.
The analog output is galvanically isolated. It can be either active (which means that the
receiving device must be passive) or passive (which means that the receiver must supply the
power for the current loop). It is recommended to use a receptor with an input resistance of
less than 700 Ω to guarantee correct operation.
The configuration of the analog output mode (active or passive) is done by means of the
connection to the terminal strip. For active mode, terminals “+” and “mA” are connected. For
passive mode, terminals “mA” and “-” are connected.
NOTE: The analog output has protection against reversed polarity. Due to another
protection against over voltages, if a loop supply voltage of more than 32 V is connected the
converter may be damaged.
