Key Technical Specifications

This GE IS200VTCCH1C IS200VTCCH1CBD board operates from a 24V DC power supply. It terminates 16 thermocouple input signals for turbine control systems. The unit measures 22 cm in length, 17 cm in width, and 4.5 cm in height. Its total weight reaches 0.7 kg without any packaging materials.

The GE IS200VTCCH1C IS200VTCCH1CBD includes 16 differential thermocouple channels with cold junction compensation. Additionally, it features one 50-pin ribbon connector for host interface. A single 6-pin terminal block connects the DC power input. The board contains 16 analog conditioners, 1 FPGA, 8 voltage regulators, 24 resistors, and 18 capacitors.

GE IS200VTCCH1C IS200VTCCH1CBD stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for input filtering. Consequently, the board maintains stable readings during 20 millisecond power fluctuations. Therefore, temperature measurements remain accurate in noisy industrial environments.

Design and Integration

Both the GE IS200VTCCH1C and IS200VTCCH1CBD versions share identical thermocouple conditioning circuitry. These boards use four-layer PCB construction with guarded analog traces for noise rejection. Consequently, the GE IS200VTCCH1C IS200VTCCH1CBD operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 150 mA typical current from the 24V DC supply. Each input channel includes software selectable filtering and burnout detection. We recommend using thermocouple extension wire for all sensor connections.

Practical Application

This thermocouple input board connects temperature sensors to a turbine monitoring system. It terminates signals from exhaust gas and bearing temperature sensors. The GE IS200VTCCH1C IS200VTCCH1CBD then routes conditioned signals to the host controller. Therefore, it serves as the front-end termination for GE turbine temperature control systems.
