GE VMIVME4150 Isolated Analog Output Board

2026-10-27

GE VMIVME4150 12-Channel Isolated 12-bit Analog Output Board

GE VMIVME4150 is a double-height VMEbus isolated analog output board developed by VMIC (GE Intelligent Platforms). It converts digital bus commands into configurable voltage or 4-20mA analog signals, designed for turbine control and real-time simulation systems, with galvanic isolation between each channel and the VME backplane.
