Signaling
The active DC OK signal output and the floating DC OK signal contact are provided to monitor the function. In addition, the
DC OK LED can be used to evaluate the function of the power supply directly at the installation location (see output
characteristic curve).

Floating contact
Output 24 V DC
The floating signal contact opens and indicates that the set
output voltage has been undershot by more than 10 %.
Signals and ohmic loads up to a maximum of 30 V AC/DC and

currents to a maximum of 1 A (or maximum of 60 V DC with a
maximum of 0.5 A) can be switched. For heavily inductive
loads such as a relay, a suitable protection circuit (e.g.,
damping diode) is necessary.
DC OK
Active signal output
Output 24 V DC
The 24 V DC signal is applied between the "DC OK" and "–"
connecting terminal blocks and can carry up to 40 mA. This
signal output signalizes when the output voltage is more than

10% below the output voltage by switching from "active high"
to "low".
The DC OK signal is decoupled from the power output. It is

DC OK
thus not possible for parallel switched devices to provide
external supply.
The 24 V DC signal can be directly connected to a logic input
for evaluation.
