Product Introduction

The DS200RTBAG5AHC is an ultra-high-density hybrid relay output termination board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides 80 outputs across five isolated banks with mixed technologies: Bank A (16 mechanical relays, 10 A high current), Banks B, C, and D (48 mechanical relays total, 5 A each), and Bank E (16 solid state relays, 2 A, <100 µs fast switching).

The “5AHC” suffix indicates a penta-bank hybrid configuration—the absolute highest channel count and most versatile RTBA board ever produced for Mark V. It is designed for the largest turbine control systems requiring a complete mix of load types: heavy motor starters (Bank A, 10 A), general purpose solenoid and indicator control (Banks B–D, 48 relays at 5 A), and high-speed PWM control or silent switching (Bank E, SSR). All on one board, one rack slot, with five-way bank-to-bank isolation. Maximum density. Maximum flexibility. Maximum integration.

Key Selling Points & Differentiators

• 80 outputs, five technologies, one slot – Bank A: 10 A mechanical for heavy loads. Banks B, C, D: 5 A mechanical for general purpose (48 relays total). Bank E: 2 A SSR for high-speed/silent switching. Replaces up to five separate boards. Saves four rack slots.
• Bank A (10 A high power, fixed terminals) – Switch motor starters (1 HP), large solenoids, pump contactors. Fixed screw terminals rated for 10 AWG. Bifurcated silver-tin oxide contacts. Red + green LEDs. External coil power option. Thermal pad required for loads above 5 A average.
• Banks B, C, D (5 A general purpose, removable terminals) – 48 relays total for smaller solenoids, relay coils, indicator lights, annunciators. Removable screw terminal blocks for easy rewiring. Color-coded per bank. Red + green LEDs. Run from backplane power (720 mA total for three banks).
• Bank E (2 A SSR, fast switching, silent) – PWM control of heaters, high-speed valve arrays, lamp testing, LED panels. Zero-crossing AC or random-turn-on DC (field selectable per group). Removable pluggable terminal blocks. Unlimited mechanical life. Only 5 mA input per channel. No coil current.
• Penta bank-to-bank isolation at 2500 VAC – Banks A, B, C, D, and E fully isolated. Connect Bank A to 240 VAC pumps, Bank B to 120 VAC solenoids, Bank C to 48 VDC battery circuits, Bank D to 24 VDC sensors, Bank E to 12 VDC fast valves on the same board.
• Mixed terminal types optimized per bank – Bank A: fixed screw (high current). Banks B–D: removable screw (convenience). Bank E: removable pluggable (fast rewiring for high-cycle applications).
• QC includes separate load tests per bank type – Bank A: 10 A resistive, 24 hours. Banks B–D: 5 A resistive, 10,000 cycles each (sample). Bank E: 1 kHz cycling, 1,000,000 cycles. All 10 bank-to-bank isolation combinations at 3000 VAC.
• 2-year warranty – Covers all 80 outputs across all five banks, external coil power circuit (Bank A), and any manufacturing defect.

Frequently Asked Questions (FAQ)

Q: What is the difference between RTBAG5A (all mechanical 5 A), RTBAG5AEB (all mechanical 10 A), and RTBAG5AHC (hybrid)?

Choose 5AHC when you need a complete mix: heavy loads (Bank A), general purpose (Banks B–D), and fast/silent switching (Bank E) in one board.

Q: Can the RTBAG5AHC fit in a standard 19-inch cabinet?
A: No. The board is 560 mm wide. Standard 19-inch rack is 483 mm. Requires 24-inch rack (610 mm internal width) or custom cabinet. We recommend minimum 600 mm internal width. For 19-inch cabinets, use RTBAG3AHC (420 mm wide, 48 outputs) or RTBAG4AHC (480 mm wide, 64 outputs).

Q: How do I use the external coil power option for Bank A?
A: Bank A (10 A mechanical relays) draws 480 mA when all 16 relays are energized. Move jumper on Bank A to “EXT.” Connect external 24 VDC supply (1 A min) to 2-position terminal block. Banks B–D run from backplane power only (720 mA total). Bank E (SSR) has no coils—5 mA per channel from backplane.

Q: What are the thermal limitations for each bank?
A: Bank A (10 A): panel mounting + forced air for 10 A on all 16 relays. Without forced air, limit 5 A. Banks B–D (5 A): panel mounting OK for 5 A on all 48 relays; DIN rail OK for 3 A average. Bank E (SSR): thermal limit 16 A total (1 A average per channel) with panel mounting. Derating chart included.

Q: The board has three different terminal types. How to replace damaged ones?
A: Bank A (fixed screw): return for repair ($65 + shipping). Banks B–D (removable screw blocks): squeeze latches, pull up. Spare blocks included. Bank E (removable pluggable): same as Banks B–D. Spare blocks included.

Q: What QC tests are specific to the 5AHC revision?
A: Standard tests per bank (coil/input, contact resistance, load tests, thermal) plus: 10 bank-to-bank isolation combinations at 3000 VAC; all 80 outputs cycled; Bank E high-cycle test (1,000,000 cycles at 1 kHz). Test report typically 20+ pages.

Q: What shipping protection for this large heavy board?
A: The 5AHC weighs 4.2 kg (9.3 lbs), measures 560 mm x 260 mm. Custom foam cradle with cutouts for all terminal types. Double-wall box with “HEAVY,” “EXTRA WIDE,” “FRAGILE,” “DO NOT STACK” labels. Shock indicator. Pallet required for shipment. Each board ships individually. Thermal pad kit in separate bag.
