GE DS200DTBCG1A Contact Output Termination Module

Configured for contact output termination in Mark V drive systems, the GE DS200DTBCG1A (DTBC Contact Output Termination Module) provides direct physical/electrical execution of high-density relay signal routing and power distribution.

Hardware Specifications

GE Mark V Drive Control Characteristics

• Backplane Bus Communication Velocity: The board interfaces with the Mark V drive core to maintain deterministic relay actuation, ensuring that contact outputs remain synchronized with the system scan cycle.
• Profinet / EtherNet/IP Deterministic Networks: While the DTBC functions as a relay termination board, its signal path integrity is designed to minimize propagation delay, supporting the high-speed requirements of the Mark V turbine control architecture.
• I/O Density Scaling: The module facilitates the termination of up to 220 signal wires, providing the high-density output capability required for complex turbine control relay arrays and solenoid actuation.
• Firmware Flash Compatibility: As a hardware-based termination board, the device does not execute firmware; however, it is strictly mapped to the system I/O database, requiring precise physical alignment with the control system's logic assignments.

Frequently Asked Questions

Q: How is signal interference mitigated when routing wires to the DS200DTBCG1A?

A: Route signal wires separately from power cabling to prevent electromagnetic interference. If parallel routing is unavoidable, utilize shielded cabling or fiber optics, as the latter is immune to electrical noise.

Q: What is the function of the J15 and J16 connectors?

A: These connectors typically interface with each other to support the #16, #17, and #18 contact output circuits within the Mark V automated drive assembly.

Q: Can the board be installed in any location within the drive cabinet?

A: No. Mounting must be consistent with the cabinet's natural convection cooling path (bottom-to-top air flow) to ensure heated components remain within operational thermal limits.

Field Installation Guidelines

• Mounting: Secure the board using designated standoffs within the Mark V cabinet. Maintain clearance around air vents to support convective cooling of relay components.
• Wiring: Utilize the 2 terminal blocks for field termination of up to 220 signal wires. Ensure all conductors are stripped to the required length and tightened to specified torque to prevent intermittent connections.
• Connector Seating: Verify that all bayonet connectors (JS1-JS8, J8, J15, J16) are fully engaged and locked. Ensure nomenclature labels match the site wiring diagrams prior to applying power.
• Grounding: Maintain proper chassis bonding to the cabinet ground bus. Use shielded wires for sensitive relay signals and terminate shields to the drive's designated common ground point.
