ACO CDNVRau-I-DIN Active video splitter for DIN rail
Active video splitter for Aco video door entry systems operating in P system,
designed for DIN rail mounting. It allows splitting audio, video and power
signals (so-called bus) to four active outputs (built-in video amplifiers) and
one passive output (no amplifier).
Its special feature is smart monitoring of input and output states (correct
voltage, short circuit, etc.). In case of detection of incorrect status, e.g.
due to a short circuit in the apartment, the splitter cuts off each active
output from the door entry system, so only one apartment is disconnected and
the whole door entry system can continue to work without any problems. When the
short circuit is over, the splitter will automatically switch on the
disconnected output again. The status of each output and input is independently
checked and signaled by individual LEDs, which can indicate by flashing codes
what type of failure occurred (this facilitates the diagnosis of problems in
the operation of the entire intercom system).
Up to 5 video receivers can be directly connected to the splitter at a distance
of max. 70m (with appropriate number of power supplies; with proper system
configuration it is possible to achieve longer distance). The splitter also
allows to split the main bus into 4 outputs (using active outputs) and to
connect another splitter to the passive output. It also allows to terminate the
main bus (built-in video terminator jumper), and one of the active outputs is
additionally amplified, which eliminates the loss of video signal for long
buses.
In addition, the splitter can be powered from the main bus or from an external
15V power supply and has an additional screw output for connecting audio and
power lines.
It can be mounted on floors, in a collective point of the installation or in
the place of bus splitting. It is designed for DIN rail mounting (occupies a
width of 4 DIN modules) or surface mounting. They are compatible with ACO
devices operating in P systems, both video and audio.
FEATURES:
- connecting up to 5 receivers
- distance to the receiver: up to 70 m (with the appropriate number of
power supplies)
- possibility to extend the distance by using additional power supplies in
the system
- separation of the main bus into 4 independent outputs
- four active outputs (video amplifiers)
- one passive output for connecting another distributor or receiver
(without video amplifier)
- one active output with additional video gain "Long Dist":
approx. 1.8x (with long buses eliminates video signal loss)
- possibility to work as a through or final splitter (built-in video
terminator connected with a jumper)
- powered from the bus or from an additional power supply (distributing
power to individual outputs)
- screw terminals for connecting the power supply and a built-in jumper to
cut off the bus power
- screw terminals for audio lines
- fault tolerant video signals
- monitoring the status of inputs and outputs: supply voltage and audio
line voltage (detection of too high and too high power supply voltage, output
overload, audio line short circuit, etc.)
- individual LEDs indicating the status of each output and input
- flash codes informing about 6 different statuses (errors) of each output
and input
- automatic disconnection from the main bus of the active output when there
is a short circuit (overload) on it and/or audio line shorted
- enabling normal operation of the entire intercom system in the event of
short-circuits in premises
- automatic restoration of normal operation after short-circuit
clearance
- enables diagnosing problems in the intercom system
- Compatible with both Audio and Video systems
