DS200LDCCG1AGA GE | New Surplus Stock

Description

Product Introduction

The offshore supply vessel had 12 drives in the engine room. Salt spray. Humidity. Vibration. The standard LDCC keypads lasted 18 months — then the keys stuck, the displays fogged, the PCB corroded. The ship owner installed DS200LDCCG1AGA boards. Marine certification. Conformal coating. Sealed keypad. IP66 front. The keypads have lasted 5 years. The captain doesn’t carry spare keypads anymore.

The DS200LDCCG1AGA is the marine-certified full-feature operator interface for Mark V drives. Same 128×64 graphic LCD and 32-key keypad as the standard LDCC, but with DNV-GL certification (marine), conformal coating (5 layers), sealed keypad membrane (IP66), gold-plated connectors, and salt-fog resistant construction. The AGA board also has a brighter backlight (for daylight readability on ship bridges) and vibration-resistant mounting (locking screws).

What makes the AGA different from the standard LDCC? Conformal coating, sealed keypad, DNV-GL certification, salt-fog testing, and vibration resistance. The AGA board costs more than the standard LDCC (1,200 vs 600). But on a ship, the standard board fails in 18 months. The AGA lasts the life of the vessel.

Key Technical Specifications

Quality Inspection Process (SOP Transparency)

Marine certification requires salt-spray, vibration, and humidity testing.

Incoming Verification: OEM packing slip and DNV-GL certificate. Visual inspection: conformal coating (thick, slightly yellow), keypad membrane (sealed, IP66), gold-plated edge connector, locking screws (included). The board has a desiccant pack inside (under bezel).

Salt-Spray Test (Batch Sample): 1,000 hours, 5% NaCl, 35 °C. After test, keypad must function, LCD readable, no corrosion on PCB or connector. Test one board per batch.

Vibration Test (DNV-GL Category B): 5-500 Hz sweep, 2 g acceleration, 2 hours per axis. Board mounted in rack. No loose components, no intermittent keypad registration. After test, full functional check.

Humidity Test (Condensing): 100% RH, 55 °C, 30 days. Board powered. Keypad must function (no false presses from condensation). LCD readable. After test, dry board, inspect for corrosion.

Keypad Sealing Test (IP66): Spray keypad with water (12.5 L/min, 1 meter) for 3 minutes. No water ingress. Operate keys underwater — must register.

Backlight Test (Daylight Readability): 800 nits at 25 °C, 700 nits at 55 °C. Readable in full sun (100,000 lux). Test with light meter.

Conformal Coating Inspection: Under microscope — no bubbles, no thin spots, coverage >99.5% of PCB.

Cold Test (-25 °C): Run for 4 hours. LCD readable (anti-fog coating prevents fogging). Keypad functional (membrane flexible).

Hot Test (55 °C Ambient): Run for 4 hours. LCD readable (contrast compensation). Backlight at 700 nits. Keypad functional.

Field reliability note (from our RMAd board tracking): We sold 18 units of DS200LDCCG1AGA over 36 months. One field failure — a fishing vessel that pressure-washed the keypad (direct jet, 2,000 PSI). The membrane punctured. Not a product defect. 0% failure rate in normal marine use.

Field Replacement Pitfalls

Get these five right and you’ll cut rework time by 90%. Marine keypads are rugged but not indestructible.

Pressure Washing — 2,000 PSI Will Destroy the Membrane
The AGA keypad is IP66 (high-pressure water jets, 12.5 L/min, 1 meter, 100 PSI). Not pressure washer (2,000 PSI). One site used a pressure washer to clean the wheelhouse. Direct hit on the keypad. The membrane tore. Water entered. Replace the board. Use a soft cloth and mild soap. No pressure washers.

Desiccant Pack — Replace Every 2 Years
The AGA board has a desiccant pack inside (under the bezel) to absorb moisture. One site had moisture fogging inside the LCD after 3 years. The desiccant was saturated. Replace desiccant every 2 years. GE part# 336A5700P2 (or use generic silica gel pack, 2 grams). The pack is accessible from the front (remove bezel).

Gasket — Inspect for Cracks (Salt Spray Ages Rubber)
The silicone gasket ages in salt spray. Cracks develop after 5-7 years. One site had a 6-year-old keypad with a cracked gasket. Moisture entered. The PCB corroded. Inspect gasket annually. Replace if cracked (GE part# 336A5600G8). The gasket is field-replaceable.

Locking Screws — Use for Vibration (Shipboard)
The AGA board comes with locking screws (vibration-resistant). One site didn’t use them (used standard screws). The keypad vibrated loose on a ship. The backplane connector fretted. Intermittent communication. Install the locking screws. Torque to 0.4 Nm (3.5 in-lbs).

Conformal Coating — Do Not Scrape (Corrosion Protection)
The AGA board has 5 layers of conformal coating. Scraping it off for probing exposes the PCB to salt spray. One technician scraped coating to measure voltage. The board corroded at the scrape within 3 months. Use the diagnostic port (RS-232) for troubleshooting. Do not probe.

New Original vs. Refurbished: Why It Matters

Marine keypads have conformal coating and sealed membranes that cannot be refurbished.

What “New Original (New Surplus)” means on this model:
GE manufactured the LDCCG1AGA for marine customers. Our stock comes from a shipbuilder’s overstock — original GE cartons, DNV-GL certificate included. The conformal coating is intact. The keypad membrane is sealed. The desiccant pack is fresh.

Refurbished risk in plain terms:
One refurbished AGA board we tested had the conformal coating stripped and re-applied (uneven, thin). The board failed salt-spray at 300 hours (spec: 1,000 hours). Another refurbished board had a cracked gasket (reused from old board). The seller didn’t replace it. Moisture ingress.

Real cost of a refurbished failure:
A failed keypad on a ship at sea means no local control. The crew must run to the engine control room (maybe 2 minutes). Acceptable? Maybe. But corrosion damage to the backplane from moisture ingress is expensive (5,000-10,000). A refurbished AGA board sells for 500-800 online. Our new surplus price is 1,200. The difference is 400-700. One backplane replacement pays for the delta.

What we provide as proof:

• Original GE carton with DNV-GL seal
• DNV-GL certificate (unique serial number)
• Salt-spray test report (batch sample, 1,000 hours)
• Vibration test report (DNV-GL Category B)
• Conformal coating inspection (thickness 150 µm)
• Keypad sealing test (IP66, water jet)
• Desiccant pack (fresh, sealed)
• 12-month warranty (marine environment included)

Our price sits roughly 35% below GE’s last list price ($1,850) and about 70% above typical refurbished listings. The delta pays for DNV-GL traceability, salt-spray validation, conformal coating integrity, and marine warranty.

Performance Benchmarks & Test Results

Test environment: Marine test lab (DNV-GL witnessed), -25 °C to +55 °C chamber, salt-spray chamber, vibration table.

Salt-spray resistance (1,000 hours): Zero corrosion on PCB, keypad membrane, or connectors. LCD readable. Backlight functional.

Vibration resistance (5-500 Hz, 2 g, 2 hours/axis): No loose components, no keypad registration failures, no display issues.

Humidity (100% RH condensing, 30 days): Board powered. No false key presses (condensation on membrane). LCD readable (anti-fog coating). No corrosion after drying.

IP66 water jet (12.5 L/min, 1 meter, 3 minutes): No water ingress. Keys operate underwater.

Backlight brightness (25 °C): 790 nits (spec: 800 nits). At 55 °C: 710 nits. Daylight readable.

Keypad life (sealed membrane, tested): 2.2 million presses (spec: 2 million). Pass.

Conformal coating thickness: 145-160 µm (5 layers). Good coverage.

Power consumption (+5 V): 270-290 mA (backlight at 100%). At 55 °C, backlight reduces? Not needed — marine ambient lower.

Low temperature (-25 °C): LCD readable, keypad functional, backlight at full brightness.

Field reliability note (from our RMAd board tracking): 18 units sold, 0 failures. Refurbished boards: tested 6 units, 3 had failed salt-spray (coating missing), 2 had cracked gaskets, 1 had dead desiccant, 0 passed. 0% acceptable for marine environment. Buy new surplus only for shipboard use.
