GE IS200TTURH1CFD is a high-reliability turbine terminal board that is a key part of GE’s Speedtronic Mark VI and Mark VIe control systems. It serves as a crucial interface connecting on-site sensors, actuators and the central control system, featuring a dual-row screw-type terminal strip to securely wire devices like proximity probes and thermocouples, while its built-in transformers, relays and passive components realize signal filtering, isolation and amplification. With 4 analog input channels (ranging from -20mA to +20mA) and 2 analog output channels, it supports both simplex and triple modular redundant architectures. Its conformal-coated circuitry enables stable operation in harsh conditions (-25°C to +60°C) and resists EMI, and diagnostic LEDs help monitor signal and power status. Widely used in power generation, oil and gas, and chemical industries, it facilitates tasks such as turbine synchronization and emergency shutdown, ensuring reliable system operation.
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.
