Product Details:

The GE IS220PSVOH1B, part number 336A5026ADP18, is a high-precision Servo Control I/O Pack Module developed for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part is dedicated to turbine servo valve closed-loop position control. As a reliable Turbine Control Module, it receives LVDT position feedback signals from fuel valves and steam valves, outputs servo drive signals to regulate valve opening, and achieves accurate flow control for gas turbines and steam turbines. It supports 8 channels of LVDT position input and 2 independent servo output channels, and can work with TSVO servo terminal boards to complete the whole servo control loop.

The GE IS220PSVOH1B Servo Control I/O Pack Module is equipped with dual 100Mbps IONet Ethernet ports for redundant network communication, ensuring stable real-time data exchange with the main controller. It supports simplex, dual and TMR redundant system architectures and allows hot replacement without full system shutdown. Front panel LED indicators display power status, communication link and channel faults in real time. Built-in comprehensive channel diagnostic functions can detect LVDT sensor faults, signal anomalies and servo drive abnormalities. The module adopts ruggedized packaging and conformal coated circuit board to resist vibration, dust and moisture in harsh power plant environments. It is widely used in power generation and oil & gas compressor stations for turbine control system maintenance, spare part replacement and system upgrade.
