4-Way Redundant Intelligent Fieldbus Junction Box

Our Bulletin 1788 4-way Redundant Intelligent Fieldbus Junction Box provides a simple, redundant, and fault-tolerant method for connecting field devices to a Profibus-PA or FOUNDATION Fieldbus (H1) network. The unit provides segment protection to four field device drop-line ports by continuously monitoring drop currents and disconnecting a faulty drop to protect the rest of the segment when a fault is detected. Trunk monitoring in redundant configurations enables the rerouting of trunk messages around cable faults.
