GE IS200TBCIS2CCD is a core terminal board interface module under GE’s Speedtronic series, tailored for the Mark VI/VIe control systems widely used in turbine operations. It serves as a key link between control processors and field sensors/actuators, supporting diverse signals such as thermocouples, RTDs, 4 – 20mA current signals and 24V DC digital signals, while completing signal conditioning, isolation and conversion automatically. Each input is optically isolated, and it has six field contacts with noise suppression filters to ensure stable signal transmission. With dual – channel redundant configuration and built – in self – inspection, it achieves real – time fault monitoring, and its – 20°C to +70°C operating range adapts to harsh power plant environments. It communicates with control processors via the VME64x bus and is compatible with ControlST software, playing an irreplaceable role in gas/steam turbine speed control, temperature monitoring and overspeed protection in power generation fields.
STAI INSTALLATION:
A sheet metal carrier that is mounted on a DIN rail carries the STAI together with a plastic insulator. The STAI plus insulator can alternatively mount to a sheet metal assembly before being fastened directly to a cabinet. There are two different varieties of Euro-block terminal blocks available:
- A permanently mounted terminal block with 48 terminals is present on STAI 1.
- A right-angle header on STAI 2 accepts a variety of pluggable terminal blocks that are readily accessible and have a total of 48 terminals.
- Typically, shielded twisted pair (#18 AWG) wires are utilized. There is an I/O cable shield terminal available next to the terminal blocks.
It is possible to accept the following analog input and output types:
- Two-wire transmitter with analog input.
- Three-wire transmitter with analog input.
- Four-wire transmitter with analog input.
- An externally powered transmitter with an analog input.
- Analog input, 5 and 10 volts direct current.
- 0-20 mA current analog output.
- Analog output, current of 0-200 mA.
