Signal Loop

Signal loop

The two signal outputs described above can be easily

combined.

Example: Monitoring two devices

Use the active alarm output of device 1 and loop in the

floating alarm output of device 2. In the event of an error, a

group error message is output. Any number of devices can

be looped. This signal combination saves wiring costs and

logic inputs.

Status Indicator: DC OK LED

The green DC OK LED enables local function evaluation in

the control cabinet.

Output Characteristic Curve

Output characteristic curve

nominal voltage. In the event of heavier loads the working

point demonstrates the U/I characteristic curve shown in

secondary voltage is reduced until the short circuit on the

secondary side is removed.

The U/I characteristic curve ensures that both heavy

capacitive loads and loads with DC/DC converters can be

supplied by QUINT POWER in the input circuit. Connected

fuses are tripped. The selectivity in your system

configuration is ensured at all times.
