Multi-Channel Fieldbus Junction Boxes from Turck

A 12-channel junction box has been added to Turck's JRBS series, which previously consisted of 4, 6 and 8-channel versions. The IP20 junction boxes that can be fitted vertically and horizontally on the top-hat rail are also available with removable screw terminals instead of the usual cage clamp terminals.

Tje JRBS junction boxes can be used in Zone 2 and Zone 1 for the simple and reliable connection of Foundation Fieldbus or Profibus-PA field devices. A coded rotary switch allows the user to set the short-circuit current as required. Operating voltage and short-circuits are indicated via LEDs for each spur line. The junction boxes allow different shielding concepts and can be terminated if required using a switchable terminating resistor.
