7.3.3

Quadrature Pulse Output (QUAD, Option D0/DE)

For the D0/DE option, the DON devices come with 2 independent hall-sensor
elements. The hall-effect sensors are arranged so that they emit separate phase-
shifted signals to one another.
The QUAD output is best-suited for verified use with a redundant signal or for
counting bidirectional currents (detecting the current direction).

Max. output current per channel (power source or sink):

100 mA (short-circuit

protected).

The current direction of the medium is defined as follows:
a.) Hx signal leading over Dx signal: Current flowing in the direction of the

marked arrow (positive)

b.) Hx signal lagging behind Dx signal: Current flowing against the direction of the

marked arrow (negative)
