When the space temperature rises to 73 °F, the voltage supplied to
the V-out board from the SAT II controller will be 8 VDC which
will cause the chip switch to open. As the space temperature drops
to 72 °F, the voltage supplied to the V-out board will be 7 VDC
which will cause the chip switch to close.
The V-out board can convert from 1 to 8 of the analog outputs
to binary outputs. One digital to analog converter (DAC or V-out
module) is required for each set of 4 analog outputs to be converted
to binary outputs. Therefore, if 1 to 4 analog outputs are to be
converted to binary outputs, 1 V-out module is required, and if 5
to 8 analog outputs are to be converted to binary outputs, 2 V-out
modules are required. One chip switch is required for each binary
output. The DAC module(s) and chip switches must be ordered
separately.
