SpliTConnect Tap

Uses

The SpliTConnect tap allows a PROFIBUS-PA bus segment complying with IEC
61158-2 to be implemented with DTE attachment points. Using the SpliTConnect
coupler, it is possible to cascade SpliTConnect Taps to create a PROFIBUS-PA
distributor. By replacing the contact screw with the SpliTConnect terminator, the
SpliTConnect tap can be used as a bus terminating resistor.

Design

The SpliTConnect tap has a sturdy plastic casing of PBT
(polybuthylene–terephthalate) complying with IP67 and is suitable for mounting on
a rail or wall. The integrated metal casing ensures complete shielding. In
conjunction with the FastConnect LAN cable for IEC 61158-2, the SpliTConnect
tap represents a simple cable attachment that can be installed quickly.
FastConnect LAN cables for IEC 61158-2 are contacted and connected using
insulation displacement terminals with contact screws. It is also possible to ground
the SpliTConnect tap using the contact screw.
