Type OA
An active 24V DC transistor output is available with this option. Max. driving capacity 400mA@24V
DC.
Fig. 26: Terminal connections - Active transistor output (OA).
Type OR
An isolated mechanical relay output is available with this option. Max. switch power 240V 0,5A. Be
sure that the output frequency does not exceed 5Hz, else the relay life time will be reduced
significantly.

4.7.3 TERMINALS 5-7: FLOWMETER INPUT
Three basic types of flowmeter signals can be connected to the F030-P: pulse, active pulse or coil.
The screen of the signal wire can be connected to the common ground terminal. See paragraph 4.5.
The input signal type has to be selected with the correct SETUP-function (read chapter 3.3.2).
On terminal 7, the internal or external sensor supply is available. To configure the sensor supply,
see paragraph 4.5.5: Sensor supply for details.
Coil-signal
The F030-P is suitable for use with flowmeters which have a coil output signal.
Two sensitivity levels can be selected with the SETUP-function:
•
COIL LO: sensitivity from about 90mVp-p.
•
COIL HI: sensitivity from about 20mVp-p.
•
Type ZF (option): offers for setting COIL HI : sensitivity from about 10mVp-p.
•
Type ZG (option): offers for setting COIL HI : sensitivity from about 5mVp-p.
