Product Introduction

The DS200SDCIG1AEB is a high-current servo interface and signal conditioning board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides 100 mA output drive capability per channel—ten times the current of standard SDCIG1 boards (10 mA)—while maintaining signal conditioning and protection features.

The “AEB” suffix indicates a high-current variant. Standard SDCIG1 outputs are current-limited to 20 mA. The AEB delivers 100 mA per channel, sufficient for direct-drive proportional valves and high-current torque motors that cannot be driven by standard boards. It includes thermal protection per channel, adjustable current limit (10–120 mA), and short-circuit protection. Use this board between an SDCC servo controller and high-current valves when the SDCC’s 10 mA output is insufficient.

Key Technical Specifications

Key Selling Points & Differentiators

• 100 mA output per channel – Ten times standard (10 mA) and five times SDCIG1A (20 mA). Drives direct-drive valves directly.
• Adjustable current limit (10–120 mA) – Configure via external controller or preset via jumpers. Protects valve coils.
• Thermal protection per channel – Independent shutdown at 85°C per channel. Fault LED indicates which channel overheated.
• Short-circuit protection – Foldback limiting, auto-recovery. Outputs can be shorted indefinitely without damage.
• Heatsink included – Required for operation above 50 mA per channel.
• Same signal conditioning as standard – 1 kHz output filtering, 100 Hz feedback filtering, surge protection, isolated loop power.
• QC includes 100 mA burn-in all channels – 24 hours at 100 mA into 100Ω load per channel.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SDCIG1A (20 mA), SDCIG1AEB (100 mA), and SDCCG1AEC (100 mA with PID)?

Use SDCIG1AEB when you already have an SDCC servo controller (or other ±10 V source) but need higher output current to drive the valve. Use SDCCG1AEC when you need both PID and high current in one board.

Q: What is the output current derating vs temperature?
A: At 25°C: 100 mA continuous. At 50°C: 75 mA continuous. At 65°C: 50 mA continuous. Heatsink included is sufficient for these deratings. For higher currents, forced air cooling required.

Q: Can I set the current limit without an external controller?
A: Yes. The board has DIP switches to preset current limit: 10 mA, 20 mA, 50 mA, 75 mA, 100 mA, 120 mA. Default: 100 mA. No software needed. See switch settings on board silkscreen.

Q: What happens if I exceed 100 mA?
A: The current limit circuit activates, reducing output voltage to maintain programmed current limit. For example, 50Ω load at 10 V would draw 200 mA. Current limit set to 100 mA reduces output voltage to 5 V. Valve may not reach full stroke.

Q: What QC tests are specific to the AEB revision?
A: Standard tests plus: output current capability (100 mA into 100Ω), current limit accuracy (programmable settings), short-circuit test (foldback, recovery), thermal shutdown per channel (85°C), derating verification at +65°C, heatsink thermal imaging.

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle with heatsink cutout, double-wall box with “HEAVY” label. Each board ships individually. Thermal pad kit included. Current limit configuration guide included.
