QUINT-PS-100-240AC/48DC/10
Floating contact
The floating signal contact opens and indicates that the set
13
14
+ + – –
output voltage has undershot by more than 10%. Signals and
ohmic loads of up to a maximum of 60 V and currents of up
to a maximum of 0.5 A can be connected. A suitable protec-
tive circuit (e.g. free-wheeling diode) is necessary for heavily
inductive loads such as a relay.
DC OK
max. 60 V AC/DC, 0.5 A
Active signal output
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".

40 mA
Device 1
Output 24V DC
DC OK
Device 2
Output 24V DC
The DC OK signal is decoupled from the power output. It is
thus not possible for parallel switched devices to provide ex-
ternal supply.
The 24 V DC signal can be directly connected to a logic input
for evaluation.
Signal loop
Monitoring two devices: Use the active signal output of de-
vice 1 and loop in the floating signal output of device 2. In the
13

event of malfunctioning, a common alarm is output. Any
number of devices can be looped in. This signal combination
saves wiring costs and logic inputs.
