Description

MRP680489 IS200VTCCH1CBB printed circuit board

The IS200VTCCH1CBB is a thermocouple input board designed by General Electric for its Mark VI system. The Mark VI is specifically designed for the management of gas and steam turbines. The system is designed to be scalable and can be used in both large and small turbine installations. The Mark VI’s hardware and software are designed with the best turbine performance in mind and specifically designed for these ultimate uses. The system provides triple redundant backup on key controls. This usually occurs in the control module, which is connected to the HMI/ operator interface, allowing users to access system data, alarm status, and maintenance tools.

IS200VTCCH1CBB is marked with several codes, including 94VO,E99006,Type 6, and 2606. The GE mark is on the board and the front panel. The front panel is attached to the PCB via screw connections and consists of three LED components that are stacked one on top of the other near the top edge of the board.

The IS200VTCCH1CBB accepts type E,J,K,S and T thermocouples. These can be grounded or ungrounded. Thermocouples can be up to 300 meters away from the control cabinet. The maximum bidirectional cable resistance is 450Ω. Thermocouples that are considered “beyond hardware limits” are taken out of the scanned input to prevent data from affecting other inputs.

The IS200VTCCH1CBB has two backplanes (P1 and P2,) and four other connectors. On the circuit board are inductors or magnetic beads (L1 to L19). It also has TP test points, diodes, resistors and capacitors. Integrated circuits include Xilinx Spartan XCS30 FPGA, IDT S35J dual-port SRAM chip, DSP TMS320C32PCMA50 digital serial processor and IDT S15Y CMOS static RAM chip.
