Type AB:
An active 0-20mA signal proportional to the flow rate is available with this option.
Max. driving capacity 1000 Ohm @ 24VDC. (Requires power supply type PD/PF/PM).

Type AF:
For the Intrinsically safe floating 4-20mA signal: please read Chapter 5.
Type AI:
An isolated 4-20mA signal proportional to the flow rate is available with this option.
When the output is disabled, a 3.5mA signal will be generated on these terminals.
Max. driving capacity 1000 Ohm @ 30VDC. This option can be used with a battery powered unit but
the life time of the battery is about 2 -3 years.

Type AP:
A passive 4-20mA signal proportional to the flow rate is available with this option. When a power
supply is connected but the output is disabled, a 3.5mA signal will be generated.
Max. driving capacity 1000 Ohm. This output does loop power the unit as well.
