Product Description:

The C9900-K631 extender kit is a signal-interface accessory produced by Beckhoff within the C9 PC Accessories series. It routes DVI-D video and USB data from a control-cabinet PC to a remote HMI, supplying a fixed overall connection length of 5.00 m between the two stations. By bundling matched cables with a rail-mounted transceiver, the part simplifies installation in tightly packed automation panels and preserves the deterministic input response needed for motion control and visualization tasks. The kit operates passively, so it neither re-clocks nor compresses data. This avoids additional processing delays when keyboards, pointing devices, or touch screens are connected.

The bundled DVI segment measures 5.00 m and terminates with DVI-D 18+1-pin male to M16 19-pin female fittings, allowing the digital stream to exit the cabinet through a sealed bulkhead and plug directly into the operator panel. A 7.3 mm overall diameter limits bend strain inside wiring ducts, while the PVC jacket withstands lubricants commonly present around machinery. The extender module itself snaps onto a 35 mm DIN rail, keeping airflow unobstructed. Maintaining impedance along this length prevents skew so full-resolution images reach the display without pixel jitter.

For peripheral channels, the host side uses a lead with USB A male to USB B male ends, and its conductors follow a 1 x 2 x 28AWG + 2C 20AWG layout over a shielded span of 1.00 m. After this patch, signals travel over a 5.00 m field cable built to Cat.5 geometry, jacketed in PUR, and wired as RJ45 8-pin to M9 8-pin so the panel can be disconnected without disturbing cabinet hardware. Compliance with USB 2.0 keeps handshake timing intact, and the link sustains a throughput of 480 Mbit/s despite the extended segment, thanks to the eight-core 4 × 2 × AWG26/7 twisted-pair design.
