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.
Features
- Protects the integrity of a FOUNDATION Fieldbus H1 or Profibus-PA segment by automatically isolating faulty drops and restoring power when faults are corrected
- Provides trunk open-circuit and short-circuit monitoring and reroutes trunk connections for extended availability
- Displays useful field bus diagnostic information via status LEDs
