About the IS200TBCIS2C

The IS200TBCIS2C is a printed circuit board (PCB) originally designed by GE Industrial Systems for use within the Mark VI Series turbine control systems. It functions specifically as a Contact Input Termination Board and represents an enhanced revision (C-rated) of the earlier IS200TBCIS2 PCB.

Although a dedicated instructional manual for this exact model is not widely available online, available documentation for related products and a detailed technical inspection provide insight into its design and function.

Hardware Overview and Functionality

• The IS200TBCIS2C accepts 24 dry contact inputs, making it an essential component for connecting terminal inputs within the Mark VI control system assemblies.

• These dry contact inputs draw power from a floating power supply within the turbine control system.

• Each input is optic-isolated and sampled at the system frame rate to ensure reliable control functionality.

• The board distributes contact input signals via three labeled plugs (JR1, JS1, and JT1) to three separate VME board racks.

• This module is part of the Mark VI Turbine Control System Series, incorporating the patented GE Speedtronic control technology.

Hardware Features

• The three plugs (JR1, JS1, JT1) interface with corresponding J3-labeled plugs on the VCCC Contact Input Board.

• The board contains six field contacts, each with its own noise suppression filter to improve signal integrity.

• The IS200TBCIS2C is also compatible with the VCRC Module, a single-slot alternative to the VCCC Contact Input Board.

• To protect the hardware, the PCB features a specialized S-style conformal coating, enhancing durability and reliability in industrial environments.

Additional Details

• The IS200TBCIS2C PCB is domestically manufactured in the USA.

• It belongs to Group 2 of the Mark VI Series.

• The C-rated functional revision indicates updates and improvements over prior versions.

• The board’s acronym “TBCI” refers to its role as a Contact Input Termination Board.
