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.


This board supports jumper-selectable output ranges, built-in overvoltage protection and channel readback registers. It is a discontinued legacy spare, commonly paired with VMIVME1150 DI and VMIVME2170A DO boards to complete closed-loop analog control racks.
