The IS200BICRH1A is a GE printed circuit board component manufactured for their Mark VI system. The MKVI is the fifth release of the successful Speedtronic series for gas/steam turbine management. This series has been in use since the release of the Mark I in the 1960s. Since then, General Electric has developed and improved several new versions of the Speedtronic management system using the best technology available at the time of release. The Mark VI has a Windows PC-based operator interface loaded with proprietary software from GE like their Control System Toolbox and Cimplicity graphics.
The IS200BICRH1A functions within the Mark VI system as a bridge interface board. This board is used in Innovation Series Medium Voltage/GP Type H drives and provides an interface between the bridge and the drive control.
The IS200BICRH1A has eight digital optically isolated inputs and outputs. It has three analog feedback inputs, including one at 0-10V and two at 0-20 mA. The backplane connector marked P1 is used for fault string, isolated I/O and bridge control. The backplane connector marked P2 is used for control board interface and logic power supply connections.
The IS200BICRH1A includes eight relay outputs (solid state) that route to the CTBC terminal board through a CABP board. Each of these outputs is indicated by a yellow LED and is optically isolated from the control.
The IS200BICRH1A has two terminal boards mounted in the front faceplate. These are marked TB1 and TB2. The board has two backplane connectors, eighteen LEDs, two fuses, and eight user TP test points. The board has more test points, they are not relevant to the end user. All test points for the end-user are accessible via an opening in the board’s front faceplate.
