FOUNDATION Isolated Device Coupler (FIDC), bus-powered
FOUNDATION Device Coupler
The FieldConnex® FieldBarrier is the first fieldbus coupler to implement
the High-Power Trunk Concept for Zone 1/ Div. 2 with galvanic isolation.
Devices can be mounted in Zone 0/ Div. 1, and are connected one device to
each output. Outputs are intrinsically safe Ex ia.
Live work on field instruments is permitted. Each output is equipped with
short-circuit protection preventing unintentional shorts and faulty
devices from harming communication and power supply to instruments and
hosts connected to the segment. LEDs communicate power, communication and
status of each output, e.g. short-circuit.
Pre-engineered housing solutions are available "installation ready" with
system certificate. Housing size, materials, cable glands and many
accessories are selectable.
With FieldConnex® FieldBarriers up to sixteen instruments can be
connected to a single fieldbus network. Spur cables can be up to 120 m
long and overall segment length is 1900 m. The maximum distances
specified for FOUNDATION Fieldbus H1 can be achieved.
