Terminal 07-08; basic POWER SUPPLY - type AP - output loop powered
:
Connect an external power supply of 8-30VDC to these terminals or a 4-20mA loop.
Do connect the "-" to terminal 7 and the "+" to terminal 8. When power is applied to these terminals,
the (optional) internal battery will be disabled / enabled automatically to extend the battery life time.
Terminal 07-08 analog output (SETUP 7) :
An analog output signal proportional to the flow rate is available as standard.
Type AA:
An active 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 @ 24VDC. (Requires power supply type PD / PF / PM).
Fig. 13: Terminal connections - 4-20mA analog output (typical)
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.
