The GE VMIVME-4514A represents GE Industrial Automation’s flagship VMEbus-based analog I/O solution, designed for critical process monitoring in nuclear power plant control systems. This 16-channel scanning analog board delivers 0.003% FSR accuracy with 16-bit resolution, specifically engineered for reactor coolant temperature/pressure surveillance. The VMIVME-4514A integrates patented Auto-Zero™ calibration technology that compensates for thermal drift in gas turbine performance monitoring applications.
As part of GE’s VME-4000 High Availability Series, the GE VMIVME-4514A supports MIL-STD-810H compliant operation in naval propulsion control rooms. Its dual-redundant P2 connector architecture ensures <1μs latency synchronization across 32-node clusters in particle accelerator facilities. The board’s radiation-hardened design maintains ±0.01% linearity after 10,000Gy total ionizing dose exposure in space launch systems.
