Honeywell 19＂RACK BGTE REDUNDTRack Enclosures

Configured for high-availability control architectures, the Honeywell 19" RACK BGTE REDUNDANT (19'' RACK BGTE Rack Enclosure) provides direct physical housing and bus management for redundant controller systems in DCS networks.

Suffix Breakdown & Model Matrix

• 19" RACK: Denotes standard 19-inch equipment width compatibility for industrial chassis.
• BGTE: Specifies the backplane/bus configuration designed for redundant I/O and controller module support.
• REDUNDANT: Indicates the chassis architecture is optimized for dual-path communication and fault-tolerant failover synchronization.

Hardware Specifications

Honeywell DCS Process Control Characteristics

• System Bus Management: The integrated backplane facilitates deterministic communication between primary and redundant controller modules, ensuring system synchronization and bumpless failover during fault conditions.
• Electromagnetic Compatibility: The reinforced steel frame serves as a passive shield, suppressing electromagnetic interference (EMI) generated by high-frequency switching hardware in proximity to the system bus.
• Redundancy Support: The chassis architecture is optimized for redundant power and communication topologies, maintaining electrical isolation between redundant signal paths and minimizing common-mode noise.
• Structural Integrity: Designed to support the static load of high-density I/O arrays, the rack maintains mechanical stability under vibration, ensuring consistent pin alignment across the backplane bus.

Frequently Asked Questions

Q: Does this rack include redundant power supply modules?

A: No, this model is the structural and backplane enclosure. Redundant power supply units (PSUs) must be installed into the designated chassis slots according to the specific system power requirements.

Q: Is the backplane hot-swap capable for controller modules?

A: Yes, the BGTE architecture is designed to support the hot-swapping of controller and I/O modules, allowing for component maintenance without requiring a full system shutdown.

Field Installation Guidelines

• Mounting: Ensure the rack is bolted to a grounded structural steel member. Use vibration-dampening washers if the cabinet is installed in an environment with high-frequency industrial noise or mechanical vibration.
• Grounding: The backplane relies on a common ground reference. Connect the rack's primary chassis ground lug directly to the central instrumentation ground bus using a multi-strand copper cable.
• Backplane Seating: Verify that the system bus connector pins are free of debris. When inserting modules, ensure the locking levers are fully engaged to guarantee low-impedance electrical contact across the redundant backplane.
• Wiring: Separate the field signal cables from the power distribution wiring within the rack to prevent inductive interference with the high-speed system bus signals.
