Product Introduction

The DS200SDCIG2ABB is a high-reliability dual-channel servo interface board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides two independent servo interface channels with gold-flashed, argon-sealed relay outputs for extreme environments.

The “ABB” suffix indicates a high-reliability variant with sealed gold-flashed relays. Standard SDCIG2A relays are vented silver-alloy (oxidizes below 50 mA). The ABB uses argon-filled relays with 0.2 µm gold flash over silver alloy—reliable down to 10 mA. Conformal coating protects the PCB from humidity and corrosion. This board is designed for mission-critical applications in corrosive environments: offshore platforms, chemical plants, paper mills, or any location where standard relays fail prematurely.

Key Technical Specifications

Key Selling Points & Differentiators

• Gold-flashed contacts on both relays – Standard relays use silver alloy that oxidizes below 50 mA. ABB relays switch 10 mA signals reliably (LEDs, PLC inputs, solid state relay triggers). Tested to 1,000,000 operations at 10 mA.
• Argon-sealed relay enclosures – Standard relays are vented to atmosphere. In humid or corrosive environments (offshore, chemical plants), vented relays fail within 1–3 years. Sealed, argon-filled enclosures have no air exchange—no oxygen, no moisture, no corrosion.
• Conformal coated PCB – Acrylic coating over all solder joints and traces. Prevents condensation-induced shorts and corrosion.
• Per-channel coil test points – Two 2 mm pin jacks per relay across the coil. Measure coil voltage (24 VDC) without removing the board or probing tiny pins.
• Extended temperature range (−40°C to +75°C) – Operates in unheated enclosures and cold climates.
• Gold-plated terminal block pins – No oxidation, maintains low contact resistance.
• QC includes low-level switching test (10 mA at 5 VDC, 1,000,000 cycles) on sample relays – Verified reliability for low-current applications.
• 2-year warranty (extended to 5 years available)

Frequently Asked Questions (FAQ)

Q: What is the difference between SDCIG2A (standard), SDCIG2ABA (isolated), and SDCIG2ABB (high rel)?

Q: When do I need gold-flashed contacts?
A: When switching loads under 50 mA at less than 12 V. Examples: PLC input modules (10 mA at 24 VDC), solid state relay inputs (5–15 mA), LED annunciators (20 mA), dry contact sensing circuits. Silver contacts develop non-conductive oxide below 50 mA. Gold-flashed contacts do not oxidize.

Q: Can I replace a standard SDCIG2A with an ABB without changing my wiring?
A: Yes—electrically and functionally compatible. Same pinout, same terminal assignments. The ABB relays are Form C (same as standard). You gain low-level switching capability and environmental protection without logic changes.

Q: The relays are sealed. Can they be replaced in the field?
A: Yes, but with difficulty. Relays are through-hole soldered. Desoldering requires a vacuum station. Conformal coating must be removed first (use included touch-up pen solvent). We offer relay replacement service ($22 per relay + return shipping). For critical applications, keep a spare ABB board.

Q: How do I use the coil test points?
A: Each relay has two 2 mm pin jacks (labeled “C+” and “C-“). Insert the test probe set into a multimeter (voltage mode). Measure across the pins: should read 24 VDC ±10% when output is energized. If voltage is present but relay does not actuate, the coil is open or mechanical failure. To measure coil current: I = V / 1600Ω (should be 15 mA ±1 mA).

Q: The board has conformal coating. Can I add or repair it?
A: Yes. We include a touch-up pen with acrylic coating. If you desolder a relay, remove coating in that area with the pen’s solvent tip. After repair, apply a new layer of coating from the pen. Allow 30 minutes to cure at room temperature.

Q: What QC tests are specific to the ABB revision?
A: Standard tests per channel plus: contact resistance at 10 mA (low current, <100 mΩ), low-level switching test (10 mA at 5 VDC, 1,000,000 cycles on sample), relay seal integrity (helium leak test, sample), conformal coating inspection (UV light, no voids), coil test point verification, extended temperature test (−40°C to +75°C), humidity test (95% RH at 40°C for 240 hours, sample). Burn-in: 72 hours at +65°C.

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, hard plastic clamshell case, desiccant pack, humidity indicator card. Double-wall box with “HIGH RELIABILITY,” “HIGH VALUE,” “FRAGILE” labels. Shock indicator. Gold-plated spare terminal blocks in separate bag. Test probe set included. Conformal coating touch-up pen included. Each board ships individually. Low-level switching test report (1,000,000 cycles) included for the production lot.
