GE IS200TSVCH1A is a high-reliability servo valve control module from GE’s Speedtronic series, specifically engineered for gas and steam turbine control systems. It serves as a critical interface between the turbine controller and hydraulic servo valves, delivering precise current/voltage signals (supporting 4–20 mA and ±10 V DC) to regulate valve position, fuel flow, and inlet guide vanes—directly impacting turbine speed, load, and efficiency. Equipped with 2500Vrms galvanic isolation and advanced noise filtering, it ensures stable signal transmission in harsh industrial environments (-40°C to +85°C operating range). The module features built-in diagnostic functions, LED status indicators, and compatibility with GE’s Proficy software for remote configuration and troubleshooting, while its rugged, modular design simplifies installation and maintenance. Widely used in power generation, oil & gas, and petrochemical sectors, it plays a pivotal role in ensuring precise turbine control and operational safety.
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.
