About the Junction Boxes
The 1788-FBJB4R and 1788-FBJB6 junction boxes provide a simple and fault
tolerant means of connecting a FOUNDATION Fieldbus network. The
1788-FBJB4R connects to up to four field devices and has dual trunk input and
output connectors for use in redundant FOUNDATION Fieldbus
configurations. The 1788-FBJB6 has a single trunk input connector and trunk
output connector and connects to up to six field devices.
The junction box continuously monitors the bus current on each field device
port. If a field device port over-current fault is detected, current to the faulted
port is limited to a safe value. Even with one drop line shorted, all other field
devices are able to communicate.
