Type OR:
A mechanical relay output is available with this option.
Max. switch power 240V 0,5A per output. (Requires power supply type PD/PF/PM). Be sure that the
output frequency does not exceed 5Hz, else the relay life time will be reduced significantly.

Type OT:
A passive transistor output is available with this option. Max. driving capacity 300mA@50V DC.

Terminal 07-08; basic POWER SUPPLY - type AP - output loop powered:
Connect an external power supply of 8-30VDC to these terminals or a (0)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 8) :
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).
