GE IS200VSVOH1BDC IS200VSVOH1B Servo Control Card

Overview

The GE IS200VSVOH1BDC IS200VSVOH1B is a Servo Control Card specifically designed for steam and gas turbine control systems. It plays a critical role in controlling servo valves, ensuring precise operation. This card is ideal for applications that require accurate speed control and valve regulation. It also integrates seamlessly with servo valve interfaces or pulse rate inputs.

Key Features

Servo Valve Interface I/O: The IS200VSVOH1BDC interfaces directly with servo valves, providing selectable current drivers and feedback from LVDRs, LVDTs, and pulse-rate inputs from flow divider feedback.
Pulse Rate Inputs: Operating in a frequency range of 2-14 kHz, this card excels in managing flow divider feedback in servo loops.
Speed Sensor Compatibility: It interfaces with both active and passive speed sensors, while supporting additional passive sensors when used with a Backup Protection Module.
Coil Servo Configuration: The card supports configurations of 2 or 3 coil servos, with the 3-coil configuration being ideal for TMR (Triple Modular Redundancy) applications to boost system reliability.
LED Indicators: The card includes 3 LED indicators for monitoring operational status: Run, Fail, and Status.
