GE IS220PSVOH1B 336A5026ADP18 Servo Interface Module

The ‌GE IS220PSVOH1B (336A5026ADP18)‌ is a ‌Servo Interface Module‌ designed for the ‌Speedtronic™ Mark VIe‌ turbine control system,
specializing in precise servo valve control for turbine actuators.

1. Key Functions

Servo Valve Control‌:
Interfaces with hydraulic servo valves to regulate turbine actuator movements (e.g., fuel valves, inlet guide vanes).
Signal Conversion‌:
Converts control signals from the Mark VIe controller into analog outputs (e.g., ±20 mA or ±10 V) to drive servo valves.
Feedback Integration‌:
Processes position feedback from ‌LVDT/RVDT sensors‌ to ensure accurate actuator positioning.

2. Technical Features

Redundancy Support‌:
Compatible with ‌TMR (Triple Modular Redundant)‌ configurations for fail-safe operation.
Diagnostics‌:
Includes self-test and fault detection for servo valve circuits.
