DS200DKLBG1ABB | GE Speedtronic Module | In Stock

Description

Product Introduction

The GE DS200DKLBG1ABB is a digital combinational I/O module for the Mark V Speedtronic turbine control system. It provides 16 digital inputs and 16 solid-state outputs with acrylic conformal coating for protection against humidity and salt fog. This module is the coated version of the DKLBG1 platform.

Core advantage: The ABB suffix protects both input and output circuits from coastal and offshore corrosion. Uncoated DKLBG1 boards in salt fog environments develop leakage current on inputs (false triggers) and output MOSFET corrosion (increased on-resistance). Coated boards eliminate both failure modes. Field data from offshore platforms shows coated DKLBG1 boards have 90% lower failure rate than uncoated.

Key Technical Specifications

Key Selling Points & Differentiators

• 16 inputs + 16 outputs in one slot – High I/O density. Replaces separate input and output modules.
• Acrylic coating for coastal/offshore – Protects inputs (leakage) and outputs (MOSFET corrosion). Uncoated boards fail in 12-18 months offshore.
• Solid-state outputs (0.5 A) – Fast switching (0.1 ms), unlimited cycle life. No relay wear.
• Short-circuit protected outputs – Survives field wiring faults.
• UV-verified coating – Acrylic fluoresces blue-green under UV. Inspected for pinholes.
• Salt fog tested (optional) – Red dot boards receive 96-hour salt fog test.
• 30-day warranty with cross-ship – Coating defect or I/O failure? We send replacement same day.

Frequently Asked Questions (FAQ)

Q: What is the difference between DS200DKLBG1 (uncoated) and DS200DKLBG1ABB (coated)?
A: Conformal coating only. DKLBG1: no coating (indoor, clean). DKLBG1ABB: acrylic coating for humidity and salt fog. Electrical specifications are identical. For offshore platforms, coastal power plants, and paper mills, use ABB. For climate-controlled control rooms, uncoated is sufficient.

Q: Does the coating affect output MOSFET switching speed?
A: No – coating is non-conductive and does not affect switching. Output response remains 0.1 ms. Coating only adds surface insulation; it does not change electrical characteristics.

Q: How do you test the coating on refurbished ABB boards?
A: We inspect under UV light (365 nm) – acrylic fluoresces blue-green. Any dark spots indicate missing coating. We also perform leakage test: 500 V DC between adjacent input terminals at 95% RH. Coated boards must measure >100 GΩ. About 8% of incoming ABB boards fail – coating has pinholes. Those are stripped and re-coated.

Q: I see an ABB board with a red dot near the terminal blocks. What does that mean?
A: The red dot indicates the board received an additional “salt fog” test per ASTM B117 for 96 hours. The board must show no leakage current on inputs and no increase in output on-resistance. Standard ABB boards are not salt fog tested. We charge an extra $25 for red-dot boards. For offshore platforms, we recommend red-dot.

Q: My ABB board has an output that failed shorted (always on). Is the coating responsible?
A: No – coating does not cause output failure. The MOSFET may have failed due to over-voltage (>30 V) or over-current (>1.2 A repeated). Replace the board or repair (replace MOSFET). Coating can be stripped and re-applied after repair.

Q: How do I identify a counterfeit DS200DKLBG1ABB?
A: Genuine boards have “DKLBG1ABB” printed on the edge connector label. Under UV light, the coating fluoresces blue-green. Counterfeits often use polyurethane (no fluorescence) or no coating with fake label. Also check the output MOSFETs: genuine uses Infineon IRLR7843 (DPAK). Fakes use smaller MOSFETs (0.2 A rating). We UV-inspect and photograph every board.

Q: Can I field-coat my existing DKLBG1 board to make it an ABB?
A: We strongly advise against it. Field coating often misses the underside of MOSFETs and optocouplers. Send us your board for professional coating ($55). We strip, clean, coat, and cure.

Q: Does the coating affect the external 24 V supply for outputs?
A: No – the output power terminals are not coated (coating stops 3 mm from screw terminals). The 24 V supply connection is unaffected.

Q: What is the shelf life of ABB boards in coastal storage?
A: Acrylic coating does not degrade in storage if kept in anti-static bags with desiccant at 10-40°C. We have shipped ABB boards stored for 5 years with no coating issues. For long-term storage in coastal areas, keep in sealed bag with silica gel. We include desiccant with each order.

Q: Do you offer a version with extended temperature range (-20 to 65°C) and coating?
A: Yes – special order DS200DKLBG1BJB (cold-flex acrylic with extended temp). Lead time is 14-21 days. Cost adds $75. For offshore cold climates (North Sea), we recommend BJB. The ABB is 0-55°C only (coating may crack below -20°C, though ABB is not rated for -20°C operation). Contact us for cold-coated versions.
