Product Overview:

The DS200DTBBG1ABB is a Contact Input Expansion Termination Module designed by GE for use within the Mark V Turbine Control System Series. This board supports input termination functionality for digital signal processing in wind, steam, and gas turbine control environments. Though the Mark V is now a legacy series, it remains notable as one of the final GE product lines to implement the patented Speedtronic control system technology, originally introduced with the Mark I in the late 1960s.

The DS200DTBBG1ABB is a revised and enhanced version of the DS200DTBBG1 base model, incorporating three critical design improvements that contribute to its performance and compatibility.

Hardware Description & Features:

• Terminal Blocks:

• Two terminal blocks, each supporting 95 signal wire connections

• Connectors:

• Three 50-pin connectors labeled JFF, JFG, and JFH

• Multiple bayonet connectors for secure cable interface

• Jumpers:

• Five onboard jumpers for custom configuration options

• Standard Components:

• Includes rectifiers, diodes, capacitors, and integrated circuits

• Designed for voltage control and protection within the system

• Dimensions:

• Height: 3 inches

• Length: 11.5 inches

• Mounting: One mounting hole in each corner for secure attachment within the drive rack

Installation & Compatibility:

• The DS200DTBBG1ABB can be installed in multiple positions within the Mark V system.

• Best Practice: Install it in the same position as the original board to maintain signal integrity and proper cable routing.

• Cable Management Tips:

• Keep signal wires away from power cables to avoid electrical interference.

• Avoid obstructing airflow within the drive to prevent overheating.

• Ensure that bundles of cables do not block air vents or surround heat-generating components.

Part Number Breakdown Insight:
