7.2.3 Quadrature Pulse Output (QUAD, Option D0/DE/DA)
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)
