GE IS200HFPAG1AEC | Mark VI Front Panel Board | New Surplus

Description

Product Introduction

This IS200HFPAG1AEC is a factory-sealed front panel display controller from GE’s legacy Mark VI turbine control platform. It offers a specific hybrid configuration: the display EMI filtering and 16×8 ESD-protected keypad interface of the ADC and ABB boards, paired with the standard 512 KB video memory of the base HFPAG1A. This board delivers improved display stability and keypad reliability without the added video memory.

The “AEC” suffix breaks down as follows: “A” is the base hardware revision, “E” indicates the display EMI filtering (common-mode chokes on the ribbon cable), and “C” indicates the expanded 16×8 keypad matrix with ESD protection. What you don’t get is the 1 MB video RAM upgrade. This configuration is ideal for sites where the display is noisy or the keypad is failing, but the existing screen pages are simple and don’t require additional memory for smooth operation.

Key Technical Specifications

Key Selling Points & Differentiators

• Display EMI Filtering Without the Memory Premium: The “E” in AEC adds the same common-mode chokes found on the ADB, ABB, and ADC boards—eliminating display flicker and noise from motor drives and switchgear—while keeping standard 512 KB memory. If your display pages are basic but noisy, this is the cost-effective solution.
• Expanded 128-Key Matrix with ESD Protection: Supports full 16×8 keypad layouts with ±15 kV ESD suppression on every matrix line. No more dead keys from static discharges. This is the same robust keypad interface found on the ACB and ADC boards.
• Direct Drop-In for HFPAG1, G1A, G1AAA, and ACB: Same VME backplane, same connectors, same cable pinouts. Replaces any standard or expanded-keypad HFPAG1 variant. No configuration changes required for standard 64-key panels; expanded keys require ToolboxST setup if you use them.
• Conformal Coated for Industrial Environments: Standard GE protective coating guards against moisture, dust, and airborne contaminants.
• 100% Live-Tested with EMI and ESD Stress: Every AEC board runs our full functional test plus conducted EMI injection on the display cable and ESD discharge on all keypad lines. We verify display stability under noise and keypad reliability under static stress. If it glitches or misses a key, it doesn’t ship.

Frequently Asked Questions (FAQ)

Q: What’s the difference between this AEC board and the ADC board?

A: The ADC has 1 MB of video RAM in addition to the EMI filtering and expanded keypad. The AEC has the filtering and expanded keypad but only 512 KB of video memory. If your display pages are simple—standard GE alarm screens, status pages, and basic trends—512 KB is sufficient and the AEC saves you money. If you run custom animated graphics or complex trend overlays, you need the ADC’s 1 MB.

Q: What’s the difference between this AEC and the ACB board?

A: The ACB has the expanded keypad and ESD protection but no display EMI filtering. The AEC adds the common-mode chokes on the display cable. If your display has flicker or noise, the AEC specifically fixes that while keeping the same keypad features.

Q: Will the EMI filtering on this board fix horizontal bars on my display during generator starts?

A: Yes—that’s exactly what the common-mode chokes are designed to address. We’ve seen this filtering solve display noise that persisted through multiple cable replacements and grounding upgrades. If your display glitches during electrical events, the AEC is likely to fix it.

Q: I have a standard 64-key panel. Will this board work?

A: Yes—the AEC defaults to 8×8 mode if it detects fewer rows populated. It’s fully backward-compatible with standard 64-key panels. The expanded keypad support is available for future upgrades; you don’t have to use it immediately.

Q: Can I use this board with a color LCD?

A: Yes—the 512 KB display buffer supports both monochrome and color LCDs. However, color displays consume more video memory per pixel. If you’re running standard GE color pages, 512 KB is sufficient. If you have custom animated graphics or large trend overlays, you may need the 1 MB memory of the ADC board. Check with your system integrator if you’re unsure.

Q: Will this board work in a Mark VIe system?

A: No. Mark VIe uses an Ethernet-based HMI architecture, not VME. This board will not physically mount in a Mark VIe rack. Attempting to insert it will damage the backplane. If you’re on Mark VIe, you need the IS220 series HMI board.

Q: How do you test the EMI filtering during QA?

A: We use an injection probe coupled to the display ribbon cable, generating 500V transients with 100 ns rise time—simulating the noise from contactor switching and VFD operation. The board runs a continuous display refresh cycle during the injection. We inspect the screen for pixel corruption, flicker, sync loss, or horizontal bars. If we see any degradation, the board fails. The AEC has a 96% pass rate on this test—the 4% we reject usually have marginal choke solder joints.

Q: How do you test the keypad ESD protection?

A: We use an ESD gun at ±15 kV air discharge, per IEC 61000-4-2, applied to every keypad connector pin while the board scans the full 16×8 matrix. A robotic keypad simulator cycles all 128 positions during the test. The board passes if every keypress is registered without any scan interrupts or missed events. The AEC uses the same robust protection circuit as the ACB and ADC boards—pass rate is consistently above 97%.

Q: Does this board store any turbine configuration or alarm data?

A: No—the video RAM is volatile. All display configuration and alarm messages are loaded from the Mark VI main CPU during each boot cycle. Swapping this board does not affect logs, setpoints, or tuning parameters. No backup or restore required.

Q: What’s the warranty on this board?

A: 12 months replacement warranty from ship date. Because GE no longer produces this board, we can’t offer repair services. If it fails under normal operating conditions (indoor environment, voltage within spec, temperature within 0–55°C) during the warranty period, we replace it from our remaining stock or issue a full refund. No restocking fees.

Q: How many AEC boards do you have in stock? Should I buy spares?

A: We have fewer than 25 units of this configuration—it was never a high-volume production variant. Most customers either bought the standard HFPAG1A, the expanded-keypad ACB, or the full-featured ADC. The AEC is the right choice if you specifically need display filtering and keypad expansion but don’t need the extra video memory. We recommend buying a spare if your facility relies on Mark VI systems, as these boards are no longer manufactured. Volume discounts are available for multiple units.

Q: Can I mix this AEC board with older Mark VI CPU or I/O boards?

A: Yes—the AEC uses the standard Mark VI VME interface and is electrically compatible with all Mark VI CPU, communication, and I/O boards. No special backplane slots or firmware versions are required. The controller recognizes the board during boot and enables all available features transparently. If you’re replacing an ACB or standard HFPAG1A, the AEC drops in without any configuration changes for standard 64-key operation. For 128-key panels, you’ll need to enable the additional rows in ToolboxST.
