Analog output module receives its digital input through an RS-485
interface from the host computer. The format of the data is either
engineering units, twos complement hexadecimal format or percentage of
full-scale range (FSR),depending on the module ’s configuration. It
then uses its microprocessor-controlled D/A converter to convert the
digital data into output signals. You get a true readback of the analog
output signal from the unit ’s ADC, which independently monitors the
output. You can specify slew rates and start up currents through the
configuration software. The Analog Output Module can supply
single-channel analog output in a range of voltages or currents. They
protect your equipment from ground loops and power surges by providing
opto-isolation of the D/A output. The transformer based isolation is up
to 3000 VDC.
