In stock

Product Introduction:
The GE VMIVME4140 is a 4-channel, high-precision analog output module for VMEbus systems. The “4140” designation indicates 4 channels with the highest accuracy available in the GE VME analog output family. While it has fewer channels than the 16-channel 2540 or 4116, the 4140 offers superior accuracy, lower drift, and faster settling time, making it the board of choice for applications where every millivolt counts. It is commonly used in calibration laboratories, precision manufacturing, and scientific instrumentation where standard 16-channel boards are not accurate enough.
