Product Introduction

The DS200SDCIG2AHB is a high-current dual-channel solid state relay interface board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides two 5 A SSR outputs for direct switching of servo valve power, heater circuits, or high-current solenoids, with four 4–20 mA feedback inputs.

The “AHB” suffix indicates a high-current SSR variant (5 A). Standard SDCIG2AFB SSRs are rated 2 A. The AHB delivers 5 A continuous with a 20 A inrush rating (10 ms). Use it to interrupt servo valve power (5 A at 120 VAC or 24 VDC), switch hydraulic pump solenoid valves directly, or control heater banks. Includes heatsink (required), snubber protection on AC outputs, TVS protection on DC outputs, and <100 µs switching speed. Two valves. One slot.

Key Technical Specifications

Key Selling Points & Differentiators

• 2 x 5 A SSR outputs – 2.5x higher current than standard AFB (2 A). Switch larger servo valves, heater circuits, or high-current solenoids directly.
• 20 A inrush capability (AC mode) – Handles cold filament inrush (incandescent lamps) or capacitive loads without damage.
• <100 µs switching speed – 150x faster than mechanical relays. Use for fast fuel trips or microsecond-precision enable.
• Independent AC/DC configuration per output – Output 1 AC, Output 2 DC, or both AC, or both DC. Jumpers selectable per channel.
• Heatsink included – Required for operation above 2 A per channel.
• 4 x 4–20 mA feedback inputs with loop power – Monitor two valves (redundant feedback each). No external power supplies.
• Opto-isolation at 4000 VAC – Protects backplane from field-side surges.
• QC includes 5 A load test both channels for 24 hours – Thermal imaging verifies heatsink temperature <85°C.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SDCIG2AFB (2 A SSR), SDCIG2AHB (5 A SSR), and SDCIG2AGB (10 A mechanical relay)?

Q: Can I run both outputs at 5 A simultaneously?
A: Thermally limited. At 25°C ambient with heatsink and natural convection, both channels at 5 A will reach 85°C case temperature within 30 minutes. For continuous operation at 5 A per channel, add forced air cooling (400 LFM) or panel mount using thermal pad. Derating: at 50°C ambient with heatsink only, limit to 3 A per channel.

Q: What is the output voltage drop at 5 A?
A: AC mode: <1.5 V peak. At 120 VAC, load sees 118.5 VAC minimum—acceptable. DC mode: <1.2 V. For 24 VDC valves, load sees 22.8 VDC minimum—check valve’s minimum operating voltage.

Q: Can the AHB switch a 5 A, 120 VAC solenoid with 30 A inrush?
A: No. AHB inrush rating is 20 A for 10 ms (AC). 30 A will damage SSR. Use external interposing contactor (AHB switches contactor coil). We sell ACC-CONT-30A (30 A rating).

Q: The board has heatsink. Does it fit in standard Mark V rack?
A: PCB is 4HP (single slot). Heatsink extends into adjacent slot (requires 8HP total width). Plan layout. For tight spaces, use panel mount option (remove heatsink, mount board directly to metal panel with thermal pad). Contact us for panel mount kit.

Q: What is the leakage current when SSR is off?
A: AC outputs: <2 mA at 280 VAC. May keep small LED dimly lit. Add bleeder resistor (10 kΩ, 5 W) in parallel with load. DC outputs: <0.2 mA at 60 VDC.

Q: What QC tests are specific to the AHB revision?
A: Twelve tests: output current capability (5 A into load per channel), inrush test (20 A for 10 ms, 100 pulses AC mode), on-state voltage drop (<1.5 VAC / <1.2 VDC at 5 A), off-state leakage (<2 mA AC, <0.2 mA DC), switching speed (<100 µs DC), high-cycle test (1,000,000 cycles at 1 kHz DC mode, low current), thermal test (5 A both channels, 4 hours with forced air, case <85°C), feedback calibration (error <±0.02 mA), isolation (outputs to backplane 5000 VAC), heatsink torque verification, derating verification (3 A at +60°C ambient), burn-in (72 hours at +50°C, 3 A per channel).

Q: What shipping protection for board with heatsink?
A: Anti-static bag, custom ESD foam cradle with heatsink cutout, double-wall box with “HEAVY,” “FRAGILE,” “ESD SENSITIVE” labels. Shock indicator. Each board ships individually. Heatsink factory-attached—do not remove. Thermal pad kit in separate bag. AC/DC jumper configuration card included. Spare snubber capacitors included.
