DS3800HMPK1K1K GE | Mark VI Board 24V DC New Surplus

Description

Product Introduction

The GE DS3800HMPK1K1K is a fully populated I/O link card from the Mark VI Speedtronic series, combining factory-configured uniform analog input capability with high-performance signal conditioning, comprehensive diagnostics, advanced filtering, and external IONet termination. This variant is specifically engineered for critical turbine applications requiring consistent, high-accuracy analog measurement across all eight channels with superior noise immunity, diagnostic feedback, and mid-chain IONet placement.

What distinguishes the 1K1K suffix is its factory-set uniform configuration that enables the same high-performance signal conditioning on all eight analog channels, with the ‘K’ base model providing high-performance components, advanced filtering, comprehensive diagnostics, and external termination. This configuration is ideal for applications requiring identical input characteristics across all channels—common in multi-point temperature monitoring, pressure arrays, or vibration systems where uniform scaling simplifies configuration and maintenance. We stock verified units with logged firmware versions and complete test records. No rework, no counterfeit—just OEM-spec hardware ready for deployment.

Key Technical Specifications

Key Selling Points & Differentiators

• Uniform High-Performance Configuration: All eight analog channels identically configured for consistent measurement characteristics—simplifies configuration and maintenance across multi-point monitoring systems.
• Comprehensive Diagnostics: Per-channel fault detection, signal quality monitoring, and communication error counters—reduces troubleshooting time.
• Advanced Filtering: 50/60 Hz notch filters and low-pass filtering—superior noise rejection for installations near VFDs and heavy switchgear.
• Precision Measurement: ±0.05% accuracy at 25°C and ±0.1% across temperature range ensures reliable turbine efficiency calculations.
• External Termination: No internal 120 Ω resistor—ideal for mid-chain placement where termination is handled by dedicated terminators at network ends.
• Full Factory Test: Every unit undergoes a 24-hour burn-in with live I/O loopback, precision source calibration (verified against NIST-traceable standards), diagnostic function validation, noise immunity testing, temperature chamber verification, and communication handshake validation—includes signed QC report with measured values for all channels.
• 30-Day Compatibility Guarantee: If the module does not function in your specific firmware revision (we log the onboard firmware), return for full credit—no restocking fee.
• Anti-Counterfeit Sealed: Each DS3800HMPK1K1K ships with tamper-evident packaging and visual inspection photos taken at receipt.
• Cost-Effective Alternative: Priced 45-60% below GE’s new MSRP while maintaining OEM-spec performance through live testing.

Frequently Asked Questions (FAQ)

Can I hot-swap the DS3800HMPK1K1K while the turbine is running?
No—absolutely not. The Mark VI backplane does not support live insertion for this module. You will need a full shutdown and power cycle. In our experience, attempting hot-swap can corrupt the IONet sync and force a controller reset. Always isolate the rack before removal.

What exactly does the 1K1K suffix mean, and does it matter for my application?
Yes, the suffix is critical. Both ‘K’ suffixes indicate the same configuration on all eight analog channels, meaning the input type, scaling, and signal conditioning are identical across the board. The ‘K’ base model provides high-performance components, advanced filtering, comprehensive diagnostics, and external termination. The exact input type varies by factory specification—we can provide the specific configuration sheet for your unit upon request. If your board sits at the end of the IONet network, you will need to add external termination.

What sensor types can the HMPK1K1K be configured for?
The ‘K’ configuration can represent various input types including thermocouples (J, K, T), RTDs (PT100), 4-20 mA, 0-10 V, 0-5 V, or low-level millivolt signals. All eight channels will have the same configuration. We verify the configuration during inbound testing and can confirm compatibility for your specific sensor type.

What makes this board different from the DS3800HMPK1J1J?
The HMPK1K1K has uniform ‘K’ configuration on all eight channels, while the HMPK1J1J has uniform ‘J’ configuration. Both boards provide high-performance components, advanced filtering, comprehensive diagnostics, and external termination. The difference is in the specific input type or scaling assigned to the ‘K’ versus ‘J’ configuration. We can compare the configuration sheets for your specific units to determine compatibility.

What makes this board different from the DS3800HMPG1K1K?
The HMPK1K1K has external IONet termination required (‘K’ suffix—no internal resistor), while the HMPG1K1K has internal termination active (‘G’ suffix). Both boards provide the same uniform ‘K’ configuration, high-performance components, advanced filtering, and comprehensive diagnostics. For mid-chain installations, the HMPK1K1K is the right choice. For end-of-chain placement, use the HMPG1K1K.

What diagnostic features does the HMPK1K1K provide?
The board includes per-channel fault detection (open-circuit and out-of-range detection), signal quality monitoring (detects signal drift and noise beyond acceptable limits), and communication error counters (detects IONet packet errors, CRC mismatches, and retries). These features allow field technicians to quickly isolate whether an issue is with the sensor, the wiring, the board, or the network.

How does the advanced filtering improve measurement accuracy?
The HMPK1K1K includes onboard 50/60 Hz notch filters that attenuate power line interference by >60 dB, and low-pass filtering that reduces high-frequency noise from VFDs and other industrial sources. This results in cleaner analog signals and more stable readings in electrically noisy environments, with measurement noise reduction of up to 80% in typical industrial settings.

How do I verify if this board matches my existing firmware revision?
We log the firmware version from every unit during our inbound test. Before shipping, we can confirm whether it matches your current revision. The precision calibration constants, filter coefficients, and diagnostic firmware reside in onboard memory. A mismatch can cause scaling errors, affect filter performance, or cause diagnostics to function incorrectly. If it differs, we advise updating your controller or request a specific rev from our stock.

These are surplus units—how do I know they aren’t counterfeit or repaired?
We maintain full traceability: every DS3800HMPK1K1K is photographed upon receipt, cross-checked against GE’s OEM marking guide (including board revision, date code, and component-level verification), and tested for electrical characteristics (insulation > 10 MΩ, current draw within 5% of spec). We do not sell repaired boards—only clean, functional pulls or new surplus. The QC tag includes our test signature and a photo record of the board’s condition.

What happens if the board fails after installation?
Our standard warranty covers functional defects for 12 months from shipment. That said, we do not cover damage from ESD, incorrect wiring, or overvoltage. To be frank, high-performance boards like the HMPK1K1K are more sensitive to ESD and thermal gradients—we recommend proper grounding and handling procedures, and avoiding mounting the board near heat sources or in areas with rapid temperature changes.

Is programming or configuration required, or is it plug-and-play?
It’s “plug-and-play” only if your IONet configuration already expects an HMPK1K1K at that slot address with the correct input configuration. Otherwise, you must reconfigure the I/O map in the CIMPLICITY or Toolbox software to match the board’s factory scaling. The diagnostics and filtering are self-contained and do not require additional configuration. The board stores no user program—all logic resides in the controller. You will not lose turbine sequences by swapping this board.

What shipping and packaging precautions do you take?
Each board is placed in an anti-static bag, wrapped in ESD foam, and double-boxed with desiccant. High-performance cards with precision components, advanced filtering, and diagnostic circuitry are extremely sensitive to moisture, contamination, and thermal shock—we seal the inner bag with a tamper-evident label, include a humidity indicator card, and use anti-corrosion packaging. We’ve shipped to offshore platforms, desert installations, and Arctic sites without humidity-related failures. If you need expedited customs documentation, we include commercial invoices with Harmonized Code 8538.90.8160.
