51306673-100 | Honeywell | TDC 3000 Enhanced Processor Node Interface Card

Product Overview

The Honeywell 51306673-100 Enhanced Processor Node Interface (EPNI) card drives high-speed data execution within the Honeywell TDC 3000 Distributed Control System (DCS). This vital interface card connects central processor nodes directly to peripheral I/O subsystems, maintaining deterministic, real-time data synchronization across critical plant operations. We supply this network processing hardware exclusively in 100% brand new, original factory-sealed condition to eliminate communication lag and guarantee zero-latency field-loop performance.

Technical Specifications

Engineering Advantages

• Bridges Divergent Industrial Protocols: The onboard communication chipsets drive dual-protocol operations, handling both legacy serial channels and high-speed CAN bus diagnostics concurrently without packet collisions.

• Resolves Severe Enclosure Space Restrictions: The compact 12 × 10 × 2 cm dimensions allow plant engineers to integrate the module into crowded, thin-profile rack slots, saving valuable footprint space inside system marshalling enclosures.

• Accelerates Inter-Node Transmission Speeds: The hardware-driven interface bypasses slow software-level polling cycles, channeling raw process variables from the field I/O nests to the central controller memory at maximum backplane speeds.

• Shields Logic Circuits Against Floor Vibration: Thick, high-grade substrate material and reinforced edge connectors anchor the 0.65 kg card firmly into the chassis rails, preventing micro-fractures and signal drops caused by physical shock from nearby pumps or compressors.

FAQs

• Does this EPNI module arrive in refurbished, repaired, or pull-out condition?

  No. We stock and ship this 51306673-100 card strictly as a 100% brand new, authentic factory-sealed piece. It retains all original manufacturer barcode labels, component tracking marks, and anti-static protective bags.

• Can I swap this card out while the rest of the node chassis remains powered?

  We advise isolating the power supply to the individual chassis slot before inserting or removing the card. Hot-swapping without verified rack isolation can create electrical arcing, which risks damaging the onboard serial and CAN bus transceiver chips.

• What software steps must I perform for the TDC 3000 system to recognize the card?

  The EPNI card functions as a plug-and-play network interface module. Once you secure the card into the designated slot guides and power up the rack, the central processor node automatically scans the hardware configuration and routes data pathways based on your existing system engineering layout.
