Terminal 05-06 (R1) / 03-04 (R2); scaled pulse output
SETUP 8 (read chapter 3) determines the pulse output function. The maximum pulse frequency of
this output is 60Hz. If a relay output option has been supplied, be sure that the output frequency
does not exceed 5Hz or else the life-time of the relay will be reduced significantly.
Type OA
An active 24V DC pulse signal output is available with this option.
Max. driving capacity 50mA@24V per output. (Requires power supply type PD/PF/PM).
Fig. 9: Terminal connections - Active output (typical)
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 A) :
An analog output signal proportional to the differential flow rate is available as standard.
