The GE VMIVME2540 is a high-performance 24-channel intelligent counter/controller module designed for VMEbus-based industrial automation systems. As part of GE’s ruggedized VME product line, this module provides precise frequency measurement up to 10MHz with 32-bit resolution for critical process monitoring applications. The VMIVME2540 features programmable input filters and gate times, making it ideal for turbine monitoring, production counting, and test bench applications.
Engineered for harsh environments, the VMIVME2540 operates across -40°C to +85°C with MIL-STD-810 shock/vibration resistance. Its dual-port memory architecture enables real-time data sharing between VMEbus and local processors.

Key Features and Advantages:
Measurement precision: The VMIVME2540 achieves 0.01ppm stability with oven-controlled crystal oscillators. Its adaptive filtering eliminates signal noise in electrically noisy environments.
Flexible configuration: Six operating modes (frequency, period, etc.) with software-selectable input coupling (AC/DC). Channel-to-channel isolation prevents ground loops.
Reliability: Conformal coating protects against dust/moisture in paper mills and foundries. Built-in self-test diagnostics reduce MTTR.
Application Areas:
- Power Generation: Turbine blade vibration monitoring
- Steel Production: Rolling mill speed measurement
- Automotive: Engine test stand RPM tracking
- Semiconductor: Wafer handling robot positioning
In hydroelectric plants, the VMIVME2540 monitors generator shaft speeds with <1μs response.
