Electrical connection

Attention: We recommend using only shielded connection cables, whereby the shield must
lie on one side (on the side of the wire ends) to ground.
5.1 VT...20 with pulse output
The output signal of the Turbotron 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-switching.
The following electronic device should have a load resistance (pull-up resistor) of 5 kΩ in the
input.
Schematic diagram:
A connection is made with three leads, the supply voltage must be connected between +U and
GND (ground), the output signal can be tapped between
of the supply cables can be taken from the connection diagram on the type plate.
