Electrical Connection
Attention:
We recommend using only screened cables. Connect the shield on one side
(the wire ends) on ground.
Electrical connection with 4-pin plug M12x1:
Screw on 4-pin-plug M12x1 to sleeve and tighten plug with a starting torque of max. 1 Nm
DR08-25 with pulse output:
The output signal of DR08-25 is a flow-proportional frequency signal. The shape of the
signal is a square wave and its amplitude corresponds approximately with the supply
voltage. It is an open collector signal, NPN- or PNP-switching.
The connected electronic instrument should have a loading resistance (pull-up or pull-
down resistor) of 5 k
in the inlet.
Schematic representation:
A connection is made with three leads, the supply voltage must be connected bU
and GND (ground), the output signal can be tapped between and GND. The colour
assignment of the supply cables can be taken from the sketch on the type plate.
Colour code:
BN = brown
BK = black
BU = blue
GN = green
WH = white
R = resistor
