Features and Capabilities

Servo Valve Interface

The IS200VSVOH1BDC offers selectable current drivers for servo valve control. Additionally, the card provides feedback from LVDRs and LVDTs, which ensures accurate control. Furthermore, it supports pulse rate inputs for flow divider feedback.

Pulse Rate Input

This card handles pulse rates ranging from 2 to 14 kHz. It supports both active and passive speed sensors, which increases its versatility. You can also add up to two passive speed sensors using a Backup Protection Module.

TMR Applications

For TMR (Triple Modular Redundancy) applications, the card supports 3-coil servos to enhance redundancy. Additionally, it requires at least two LVDT/LVDRs per servo channel.

LVDT/LVDR Feedback

The IS200VSVOH1BDC can handle up to three LVDT/LVDRs per servo channel. It offers software options for median, high, or low select feedback, providing flexible control. Finally, the card supports bi-directional servo current outputs, ensuring precise operation.
