Product Details:

The GE IS220PSVOH1B is a high-performance Servo Control I/O Pack Module (PSVO) designed for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part is dedicated to high-speed servo valve closed-loop control. As a reliable Turbine Control Module, it receives LVDT/RVDT position feedback signals and pulse rate key phasor signals, outputs high-precision drive signals to servo actuators. It supports 2 independent servo control loops, accurately adjusting fuel valves and steam control valves to regulate fuel and steam flow for gas turbines and steam turbines. It needs to cooperate with TSVO series terminal boards to build a complete servo control loop.

The GE IS220PSVOH1B Servo Control I/O Pack Module is equipped with dual 100Mbps full-duplex IONet Ethernet ports for redundant network communication, supporting hot swap maintenance without system shutdown. Front panel LED indicators show power status, network link and channel fault alarms. Built-in comprehensive channel diagnostic functions can detect LVDT sensor open circuit, short circuit and abnormal servo drive signals. It adopts conformal coated PCB to resist dust, moisture and vibration in harsh power plant environments. The module supports simplex, dual and TMR redundant system architectures and I/O rack mounting inside Mark VIe control cabinet. It is widely used in power generation and oil & gas industries for turbine control system maintenance, spare part replacement and system retrofit.
