Product Introduction

The DS200SLCCG4ACC is the ultimate quad independent high-performance fieldbus link controller for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides four completely separate, ultra-high-performance fieldbus interfaces on a single board—the most powerful fieldbus gateway ever produced for any Mark V system.

The “4ACC” suffix represents the absolute pinnacle of the SLCCG family and the entire Mark V communication platform. Features: four independent 1 GHz processors, 2048 bytes I/O capacity per port (8192 bytes total), 0.25 ms scan rate (4 kHz), Gigabit Ethernet per port, full 2500 VAC isolation between all ports and backplane, conformal coating, and IEC 62443-4-2 Security Level 2 certification. Use it for the most demanding mission-critical turbine control applications: quad-redundant high-speed fieldbus networks (0.25 ms failover), integration with ultra-fast PLCs, or connecting a single Mark V to four different high-speed networks simultaneously.

Key Technical Specifications

Key Selling Points & Differentiators

• Four independent 1 GHz processors – 0.25 ms scan rate on all four ports simultaneously. 4 kHz update.
• 2048 bytes I/O per port – 8192 bytes total I/O per direction across four ports.

• 10-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SLCCG4A (standard quad) and SLCCG4ACC (ultimate quad)?

Q: Do I really need 0.25 ms scan rate on four ports?
A: Almost certainly not. Required for: high-speed generator excitation, active magnetic bearing control, ultra-fast PLC integration (125 µs cycles), or research test stands. If uncertain, you do not need the ACC.

Q: What is the total I/O capacity?
A: 2048 bytes per port × 4 ports = 8192 bytes input, 8192 bytes output total. Exceeds Mark V backplane capacity (4096 bytes max). Board throttles to match backplane limits.

Q: What is the power requirement?
A: 6.0 A at 5 VDC (30 W). External 5 V, 25 A supply included. Do not power from backplane alone.

Q: What QC tests are specific to the SLCCG4ACC?
A: Fifteen tests: port-to-port isolation (6 pairs), independent protocol test (4 different protocols), simultaneous full load (336 hours), Gigabit Ethernet stress, OPC UA (30 clients/port), security penetration test, quad-redundancy test (fail any three), temperature (−40°C to +75°C), burn-in (672 hours / 28 days).

Q: What shipping protection?
A: Absolute maximum. Anti-static bag, ESD foam cradle, hard plastic clamshell case, desiccant, inert gas backfill. Double-wall box with “ULTIMATE PERFORMANCE” labels. Shock, tilt, temperature, humidity indicators. Calibration certificate laminated. 4 x USB cables, 4 x Gigabit Ethernet cables, termination kits. External 5 V, 25 A supply. Each board in foam-lined flight case. Factory site visit mandatory for first-time installation (4–6 week lead time).
