Product Introduction

The DS200SDCIG1AHB is a high-current solid state relay interface board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides four 5 A SSR outputs for direct switching of servo valve power, heater circuits, or high-current solenoids, along with eight 4–20 mA feedback inputs.

The “AHB” suffix indicates a high-current SSR variant (5 A). Standard SDCIG1AFB 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.

Key Technical Specifications

Key Selling Points & Differentiators

• 5 A continuous SSR output – 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 contact welding.
• <100 µs switching speed – 150x faster than mechanical relays. Use for fast fuel trips or microsecond-precision enable.
• Independent AC/DC configuration per output – Each of the 4 outputs configurable for AC (zero-crossing) or DC (random turn-on) via jumper.
• Heatsink included – Required for operation above 2 A per channel. Board runs at 50°C temperature rise at 5 A.
• 8 x 4–20 mA feedback inputs with loop power – Monitor valve position on the same board.
• Opto-isolation at 4000 VAC – Protects backplane from field-side surges.
• QC includes 5 A load test all 4 channels for 24 hours – Thermal imaging verifies heatsink temperature <85°C.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SDCIG1AFB (2 A SSR), SDCIG1AHB (5 A SSR), and SDCIG1AGB (10 A mechanical relay)?

Choose AHB for 3–5 A loads requiring fast switching (SSR benefits) or where mechanical relay wear is unacceptable. Choose AGB for loads above 5 A or when NC contact is required.

Q: Can I run all 4 outputs at 5 A simultaneously?
A: Thermally limited. At 25°C ambient with included heatsink and natural convection, 5 A on all 4 channels will reach 85°C case temperature within 30 minutes. For continuous operation at 5 A per channel, you must add forced air cooling (400 LFM minimum) or panel mount the board using the thermal pad to a metal backplane. 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 (3 V total across load). At 120 VAC, load sees 117 VAC minimum—acceptable for most valves. DC mode: <1.2 V. For 24 VDC valves, load sees 22.8 VDC minimum—check your valve’s minimum operating voltage.

Q: Can I use the AHB to switch a 5 A, 120 VAC solenoid valve with a 50 A inrush?
A: No. The AHB inrush rating is 20 A for 10 ms (AC mode). A 50 A inrush will damage the SSR. Use an external interposing contactor (the AHB switches the contactor coil, which draws <1 A). For the contactor, we sell ACC-CONT-30A (30 A rating).

Q: The board has an attached heatsink. Does it still fit in a standard Mark V rack?
A: The PCB is 4HP (single slot). The heatsink extends beyond the board edge, requiring an adjacent empty slot (8HP total width). Plan your rack layout accordingly. For tight spaces, use the 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 the SSR is off?
A: AC outputs: <2 mA at 280 VAC. This may be enough to keep a small LED dimly lit. For sensitive loads, add a bleeder resistor (10 kΩ, 5 W) in parallel. DC outputs: <0.2 mA at 60 VDC.

Q: What QC tests are specific to the AHB revision?
A: Twelve tests:

1. Output current capability: 5 A into load (resistive) per channel
2. Inrush test (AC mode): 20 A for 10 ms, 100 pulses
3. On-state voltage drop: <1.5 VAC / <1.2 VDC at 5 A
4. Off-state leakage: <2 mA AC, <0.2 mA DC
5. Switching speed (DC mode): <100 µs (oscilloscope)
6. High-cycle test: 1,000,000 cycles at 1 kHz (DC mode, low current)
7. Thermal test: 5 A on all 4 channels, 4 hours with heatsink + forced air, case temperature <85°C
8. Feedback calibration: 4–20 mA, error <±0.02 mA
9. Isolation: outputs to backplane at 5000 VAC
10. Heatsink attachment torque verification
11. Derating verification: 3 A at +60°C ambient, no thermal shutdown
12. Burn-in: 72 hours at +50°C, 3 A per channel (derated for temperature)

Q: What shipping protection for this board with attached 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 is factory-attached—do not remove. Thermal pad kit (for optional panel mount) in separate bag. Torque card included.
