GE DS200CTBAG1ADD – Contactor/Terminal Board for Reliable Discrete I/O Termination

The GE DS200CTBAG1ADD is a CTBA-series terminal board typically used to terminate and distribute discrete contact signals in GE industrial control systems (often seen across Mark V and EX2000/DC2000 platforms). From my experience, it’s the board you pick when you need clean, labeled screw-terminals for field wiring and a straightforward way to hand off those signals to the controller via internal connectors—without overcomplicating the panel.

One thing I appreciate is how the CTBA layout keeps maintenance simple: barrier-strip terminals are easy to trace, and the revision level “ADD” indicates a mature hardware spin that has been widely adopted in service work. You might notice that this board is commonly stocked as a drop-in spare, which makes sense—swaps are fast and, in many cases, wiring lands in minutes.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express delivery: FedEx, UPS, DHL
• Pre‑ship checks: Visual inspection, basic continuity of terminals, and packaged with ESD-safe materials

Key Features

• Purpose-built terminal board: Provides organized screw-terminal points for discrete contact I/O, reducing wiring clutter and field errors.
• Internal ribbon/backplane interface: Hands off signals to the controller core via internal connectors—no fieldbus setup required.
• Robust barrier strips: Labeled terminals for dry contacts and relay circuits; makes loop checks and service easier.
• Revision “ADD” hardware: A later hardware revision that, in many cases, is chosen for like‑for‑like replacement in legacy panels.
• Form/fit for GE panels: Fits standard GE rack/panel layouts commonly used in Mark V or EX2000/DC2000 cabinets.
• Low maintenance: Passive design with no firmware—usually just inspect terminals and cleanliness during shutdowns.

Technical Specifications

Application Fields

This board is commonly used in:

• GE Mark V turbine control cabinets (gas/steam) for discrete contact I/O termination
• GE EX2000/DC2000 drive and excitation systems where contactor and relay circuits need organized termination
• Balance-of-plant panels requiring clean hand‑off of field dry contacts to the controller core

One maintenance lead told us, “Swapping a DS200CTBAG1ADD takes less time than re-landing a terminal strip—we keep one on the shelf because it saves a shutdown when a strip gets damaged.”

Advantages & Value

• Form, fit, function: OEM‑compatible layout that typically drops into existing GE panels without mechanical rework.
• Reduced commissioning time: Clear labeling and barrier strips speed up loop checks and troubleshooting.
• Lower risk in legacy systems: Passive design means fewer failure points; no firmware to match.
• Procurement confidence: Tested before shipment, backed by a 365‑day warranty and responsive support.

Installation & Maintenance

• Environment: Mount in a clean, ventilated control cabinet; avoid moisture and conductive dust. Follow standard Mark V/EX2000/DC2000 cabinet practices.
• Wiring: Use ferruled conductors where possible; torque screw terminals to manufacturer guidance; maintain strain relief and segregation from power cables.
• Safety: De‑energize circuits before service; observe ESD precautions; verify terminal IDs against the panel drawings prior to landing wires.
• Routine care: During outages, check terminal tightness, look for discoloration, and gently clean dust with dry air; document any re‑landed conductors.
• Compatibility checks: The suffix “ADD” denotes a later revision; in most cases it’s backward‑compatible within the same group (G1). Review your bill of materials to confirm fit.

Quality & Certifications

• Typically used inside CE/UL certified control cabinets; board-level components are manufactured to GE quality standards.
• Legacy hardware may be RoHS‑exempt depending on build date; documentation can be provided with the shipment when available.
• Each unit is inspected and functionally verified prior to dispatch; 365‑day warranty applies.
