GE IS200SCLTH1ABB Overview
Manufacturer: General Electric
Series: Mark VI Speedtronic Turbine Control
Product type: Core Analog Terminal Board (SCLT)
What is IS200SCLTH1ABB?
The IS200SCLTH1ABB is a Core Analog Terminal Board used in the GE Mark VI / Mark VIe turbine control system. It serves as a key interface board that connects turbine sensors and field signals to the control system.
It belongs to GE’s Speedtronic family of gas and steam turbine control platforms, widely used in power generation and heavy industrial environments.
Main Function
This board provides analog signal termination and conditioning for turbine control. When used together with the associated SCLS terminal board, it forms a core part of the analog I/O subsystem.
Typical signals supported
The board enables the system to read and send critical process signals, including:
- Thermocouple temperature inputs
- RTD temperature inputs
- Voltage inputs
- 4–20 mA current loop inputs
- 4–20 mA current loop outputs
These signals allow the turbine controller to monitor and control temperature, speed, pressure, and other process variables.
Role inside the Mark VI System
The Mark VI platform is a fully integrated turbine control, protection, and monitoring system. It directly interfaces with sensors and actuators without needing extra instrumentation layers.
Within this architecture, the SCLT board:
- Acts as the core analog interface
- Expands analog I/O capacity
- Helps ensure reliable turbine operation and monitoring
Hardware Features
Typical hardware characteristics include:
- Conformal-coated PCB for industrial protection
- Multiple connector ports (JT, JS, JR) for option boards
- Terminal strip for field wiring
- Designed for static-sensitive industrial environments
These features make it suitable for harsh industrial environments like power plants.
Applications
The IS200SCLTH1ABB is commonly used in:
- Gas turbine control systems
- Steam turbine control systems
- Power generation plants
- Oil & gas facilities
- Heavy industrial automation
