GE VMIVME1150 64-Channel Opto-Isolated Digital Input Board

GE VMIVME1150 is a double-height VMEbus optically isolated digital input board developed by VMIC (GE Intelligent Platforms). It provides 64 isolated digital input channels, designed to collect contact status and switching signals in industrial VME control systems, with excellent noise suppression for harsh industrial environments.

This board adopts high voltage optical isolation design, supports configurable input filtering and logic polarity. It is widely used in GE turbine control, industrial simulation and heavy-duty process control racks, and it is a classic discontinued maintenance spare part for VME I/O systems.
