Description
Overview
The IS200TPROH1B Protective Termination Card is a GE Mark VIe field‑termination module engineered to interface protection‑related wiring within turbine control systems. Designed for high‑reliability gas and steam turbine applications, this board provides secure termination points, electrical isolation, and robust surge‑protection features essential for safe turbine operation.
Functional Characteristics
The board includes two high‑density terminal blocks, each offering 24 termination points, enabling reliable connection of trip circuits, protection sensors, and shutdown wiring. Gold‑plated contacts ensure long‑term corrosion resistance and stable signal transmission in high‑vibration turbine enclosures.
The IS200TPROH1B incorporates:
-
Isolation transformers for protection‑signal separation
-
MOV‑based surge suppression for transient overvoltage protection
-
EMI‑filtering components to maintain signal integrity
-
Multiple system connectors for integration with Mark VIe control hardware
Primary connectors (JX1, JY1, JZ1) handle core protection signals, while auxiliary connectors (JX5, JY5, JZ5) support secondary functions and filtered signal paths.
