Product Introduction
Expanding I/O capacity without adding cabling is a common challenge in legacy DCS upgrades, and the solves this by leveraging Foundation Fieldbus H1 technology. This interface card acts as the critical bridge between the DeltaV controller and the field network, allowing you to connect up to 16 intelligent field devices on a single multi-drop segment.
Designed with high availability in mind, this unit features 1:1 redundancy with automatic sensing and seamless switchover to ensure uninterrupted control. The also provides synchronized control and supports third-party H1 devices, giving you the flexibility to integrate diverse field instrumentation while reducing overall wiring costs and installation complexity.
Key Selling Points & Differentiators
- High-Density Connectivity: Supports multi-drop configuration for up to 16 devices per port, significantly reducing field wiring and termination costs compared to conventional I/O.
- Built-In Redundancy: Features 1:1 redundant architecture with autosense and automatic switchover, ensuring zero-bump operation during card or network failures.
- Verified Functionality: Every undergoes a 24-hour live load test on a dedicated DeltaV test rack before shipping, complete with a signed test report.
- Not Recommended For: Do not use this card for non-H1 protocols or as a replacement for M-Series redundant power supplies; it is strictly an H1 communication interface.
- Stock Availability: Current inventory is factory-sealed new surplus with traceable lot numbers; typically ships within 48 hours of order confirmation.
- Warranty Backed: Includes a 1-year functional warranty covering manufacturing defects and DOA conditions, with no restocking fees for verified failures.

FAQ
Yes. All units in stock have passed our 24-hour live bench test and include a signed test report. We ship same-day for orders placed before 2 PM EST, so you’ll have tracking before end of day.
Is this module compatible with my older DeltaV M-Series carrier?
The is designed for M-Series Foundation Fieldbus I/O, but verify your carrier and terminal base part numbers first. Some early M-Series carriers may require a specific terminal base (e.g., with protection keys) to ensure proper mechanical and electrical alignment. Send us your carrier P/N, and we’ll confirm compatibility within 30 minutes.
What’s the difference between this and the VE4017P2 or KJ3242X1-BA1?
The suffix indicates a hardware revision or minor configuration variant. KJ3242X1-BA1 is often an alternate or legacy part number for the same H1 interface function. In most cases, they are functionally interchangeable, but the P0 may have specific firmware for certain H1 stack versions. If your system is sensitive to revisions, we recommend matching the exact suffix or consulting your DeltaV configuration database.
Do I need to reconfigure the module after installation?
No. The retains its network configuration in the DeltaV controller, not on the card itself. Simply plug it into the same slot, and the system will recognize it. However, always verify H1 device addresses, segment parameters, and redundancy settings in DeltaV Live after replacement.
What if the module fails within the warranty period?
We offer a no-questions-asked replacement for any verified manufacturing defect. Ship the failed unit back with your RMA number, and we’ll send a replacement within 24 hours of receipt. We also provide a loaner program for critical applications to minimize downtime.
Can this card support third-party H1 devices?
Yes. The is designed to support third-party Foundation Fieldbus H1 devices, provided they are certified and properly configured in the DeltaV device description (DD) files. We recommend verifying device compatibility in the Emerson interoperability matrix before deployment.
Is this a refurbished or new surplus unit?
This is New Original (New Surplus) – factory sealed, never installed, with full traceability to the original manufacturing lot. It is not refurbished, repaired, or pulled from a decommissioned system. We provide the original manufacturer’s lot code upon request for your quality records.
Quality Transparency SOP
- Incoming Verification: Source traceability confirmed via lot code; anti-counterfeit visual inspection; serial number cross-referenced with OEM records; accessories and documentation verified.
- Live Bench Test: Dedicated DeltaV test rack; power-on self-check; H1 network handshake test; 16-device multi-drop simulation; 24-hour continuous load test; signed test report generated.
- Electrical Tests: Insulation resistance verified at 500V megger (>10 MΩ); ground continuity confirmed; H1 signal integrity validated.
- Firmware Verification: Firmware version recorded; H1 stack revision documented; DIP/jumper configuration backed up.
- Final QC & Packaging: QC sign-off; anti-static seal applied; shock protection installed; QC Passed label affixed with date and inspector ID.
Test photos and video available upon request. We never claim “100% failure-free” – we provide verified, tested units with documented performance.
Technical Risk Avoidance
- H1 Segment Length: Risk: Communication failure due to excessive cable length. Prevention: Verify total segment length does not exceed 1900m (with repeaters) or 1200m (without). Field Note: We’ve seen H1 faults traced to a 1400m segment without a repeater. Check your segment design first.
- Redundancy Mismatch: Risk: Redundant card not syncing. Prevention: Ensure both cards are identical revision and firmware. Field Note: Mixing P0 and P2 cards in a redundant pair caused autosense failures. Match the suffix exactly.
- Terminal Base Compatibility: Risk: Card not seating properly. Prevention: Verify terminal base has correct protection keys for H1 cards. Field Note: Forcing a card into the wrong base bent pins. Always check the keying before insertion.
- Device Address Conflict: Risk: Multiple devices on same address. Prevention: Document H1 device addresses before removal. Field Note: A duplicate address caused the entire segment to go offline. Take a screenshot of your device list before you pull the card.
- ESD Damage: Risk: Silent H1 stack failure. Prevention: Use grounded wrist strap and anti-static mat during handling. Field Note: We’ve tested cards that passed power-on but failed H1 communication after 48 hours due to ESD. Handle with care.
