Dual Systems -- VIC 4-20 Analog To Digital Board
The VIC 4-20 converts voltage outputs from an AOM-12 into
four separate 4-20Ma current outputs.
The board provided industry-standard 4-20ma output controls. There was
overvoltage protection on all current outputs. Each output had 12-bit
resolution. Accuracy was 12-bit ± 1/2 L.S.B. from 0 to 70°C
temperature. There was also transient protection per ISA standards.
The board claimed a low drift of .01%/°C
The VIC4-20 was a voltage-to-current converter module which provided 4-20 mA
current outputs when used in conjunction with the Dual Systems
. It converted the 0-10V of the AOM-12
output to a 4-20 mA output.
The analog current outputs leave theVIC4-20 through a rugged 34-pin male PCB
header located at the top of the board. The header is arranged with
alternate ground wires between all output lines to minimize crosstalk
