PRODUCT DESCRIPTION
Splitter SD904 is designed for splitting 9 input lines (8 SAT and 1 terrestrial TV) into 2 paths. It can be used as the end tap
in cascaded branch of network.
The splitter meets shielding requirements of class A according standard EN 50083-2.
The splitter is intended for indoor use only.
SAFETY INSTRUCTIONS
Installation of the splitter must be done according IEC60728-11 and national safety standards.
Any repairs must be done by a qualified personnel.
No naked flame sources, such as lighted candles, should be placed on
splitter.
MOUNTING
The splitter
must be fixed with steel screws
Ø 4-5 mm. The screws are not included in a package.
OPERATING
Splitter SD904 consists of 9 highly isolated splitters for every input line. Splitters distribute signals into two equal parts,
maintaining line matching properties and isolation between different paths.
Connectors on splitter can accept cables with central pin diameter up to 1.2 mm.
Regarding DC both terrestrial TV branches have through pass, but current limit up to 0.1 A must be maintained.
Managing of DC pass through SAT TV lines is more complicated because of dual application of device as a splitter or tap.
The next diagrams demonstrate DC pass features for horizontal and vertical polarization lines.
