VMIVME-4150

GENERAL DESCRIPTION — The VMIVME-4150 provides 12 isolated high quality 12-bit analog output channels
on a single 6U form factor VMEbus board. Each channel is electrically isolated from all other channels and from the
VMEbus, as illustrated in the functional block diagram as shown in Figure 1, and will operate with sustained isolation
voltages as high as 1,000 V. Output voltage ranges are selectable as ±2.5, ±5, and ±10 V, or 0 to +2.5 V, 5 V, 10 V,
and full 10 mA loading is supported throughout these ranges. Four-, eight-, and twelve-channel configurations are available.
Outputs can be disconnected or placed in a minimal state under program control during system testing, and are
disconnected or placed in a minimal state automatically at reset.
Optional current-mode outputs support applications which require standard 4 to 20, 0 to 20, or 5 to 25 mA analog
current loops. Compliance of the current mode outputs is 9 V if the loop supply originates on the board, or 27 V with an
external loop power supply.
A front panel Fail LED is provided. The LED light is turned ON during system reset and can be turned OFF under user software control.
