Hardware Specifications

GE Industrial Control Characteristics

• Backplane bus communication velocity: The module serves as a passive termination interface for the TCCB board. Signal transit latency is minimized to maintain high-speed sampling rates necessary for deterministic turbine protection logic.
• Profinet / EtherNet/IP deterministic networks: While the module is hardware-analog, it provides the clean signal path required for downstream conversion to digital fieldbus protocols within the Mark V rack architecture.
• I/O density scaling: The 52-point termination density is optimized for high-density analog input monitoring, allowing for modular scaling of temperature-sensing circuits within position seven of the core cabinet.
• Firmware flash compatibility: As a passive termination component, the module requires no firmware; it maintains electrical transparency, ensuring full compatibility across all Mark V TCCB board revisions and software versions.

Frequently Asked Questions

Q: Does the DS200TBCAG1AAA require power for operation?

A: No. The module is a passive termination board designed for routing analog RTD signals. Power is provided only to the localized signal loops by the connected TCCB board.

Q: Can the jumper settings for 0-1 mA input be changed while the system is under load?

A: No. Any modification to configuration jumpers must be performed with the control rack de-energized. Adjusting jumpers while the circuit is active can result in signal transients or potential damage to the TCCB input stages.

Field Installation Guidelines

• Mounting: Utilize the integrated bayonet connectors to seat the module securely within the cabinet rack. Proper mechanical seating is mandatory to ensure low-contact-resistance paths for sensitive RTD temperature signals.
• Grounding: Ensure the module chassis is bonded to the cabinet’s analog ground reference. This is mandatory to prevent ground-loop-induced noise from injecting errors into the 4-20 mA or 0-1 mA measurement circuits.
• Wiring: Terminate field-side RTD leads to the 52 terminal points using appropriate strain relief. Maintain a minimum separation of 150 mm from high-voltage AC cabling to prevent inductive coupling, which is critical for protecting the accuracy of the temperature measurement signals.
