I/O modules

The GE IS200VVIBH1CAB (or IS200VVIBH1C) is a specialized VMEbus vibration monitoring board. This critical component acquires and processes vibration signals from machinery sensors. Moreover, it provides essential data for predictive maintenance and equipment protection in industrial systems.

Core Functionality for Machinery Health

This board interfaces directly with vibration transducers, such as the PR6423/128-110. It conditions the raw sensor signals and converts them into usable digital data. Consequently, control systems can monitor machine health and trigger alarms for excessive vibration levels.
