IS220PSVOH1B GE I/O Pack

Description

The GE IS220PSVOH1B is a Servo I/O Pack within the Mark VIe control system developed by GE Vernova. This module serves as a crucial electrical interface connecting one or two I/O Ethernet networks to a TSVO (Servo Terminal Board). Its primary function is to manage servo valve position loops, typically utilizing a WSVO servo driver module to control one or two servo valves. This precise servo control capability is vital for accurate positioning and movement in various industrial applications, particularly within the power generation and oil & gas sectors where GE's Mark VIe systems are widely employed.

Key Feature

Precise Servo Control Interface: Its primary function is to provide the necessary interface for accurate control of servo valves within the Mark VIe system, enabling precise positioning and movement of critical machinery.

Dual Ethernet Communication: Equipped with two 100 MB Ethernet ports (ENet1/ENet2) for robust and reliable communication within the Mark VIe I/O network, ensuring timely data exchange for control and diagnostics.

Direct Connection to Servo Terminal Board (TSVO): Designed to directly interface with a TSVO terminal board, simplifying the wiring and connection to servo valves and feedback devices like LVDTs.

Application

Steam Turbine Control: In power generation, this module is crucial for precisely controlling the position of steam turbine valves (e.g., control valves, intercept valves). Accurate valve control is essential for regulating steam flow, maintaining turbine speed and load, and ensuring efficient and stable power generation.

Gas Turbine Control: Similar to steam turbines, the IS220PSVOH1B is applied in gas turbine systems to manage the position of fuel valves, inlet guide vanes (IGVs), and other critical actuators. Precise control of these components is vital for controlling fuel flow, air intake, and ultimately, the power output and efficiency of the gas turbine.
