Description
Overview
The IS200TTSAG1A Turbine Emergency Trip Board is a GE Mark VIe temperature‑processing module engineered to acquire and condition thermal signals from critical turbine components. Designed for high‑integrity protection systems, it provides precise measurement, fault detection, and reliable interface capabilities for both gas and steam turbine applications.
Functional Characteristics
This module supports eight analog input channels, each configurable for multiple thermocouple types (J, K, T, E) or 3‑wire RTDs. With measurement accuracy typically within ±0.1°C, the IS200TTSAG1A ensures dependable temperature monitoring for safety‑related turbine functions.
Key features include:
-
Channel‑to‑channel electrical isolation
-
Built‑in diagnostics for sensor health monitoring
-
LED indicators for individual channel status
-
Automatic cold‑junction compensation for thermocouples
-
Lead‑resistance compensation for RTDs
-
Open‑circuit detection for fault identification
The board is compatible with TMR (Triple Modular Redundant) architectures, making it suitable for high‑availability protection systems.
Environmental and Mechanical Performance
The module is designed for harsh industrial environments and includes EMI‑hardened circuitry and a conformal‑coated PCB for long‑term durability.
