ADAM-4021 Analog Output Module

Analog output module receives its digital input through an RS-485 interface from the
host computer. The format of the data is either two's 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 will get a true read-back of the analog output signal from the unit's ADC, which
monitors the output independently. You can also specify slew rates and start up cur-
rents through the configuration software. The Analog Output Module can supply sin-
gle-channel analog output in a range of voltages or currents.
Furthermore, it will protect your equipment from power surges at the ground terminal
by providing opto-isolation of the D/A output and up to 3000 VDC transformer based
isolation.
Slew Rate
The slew rate is defined as the discrepancy between the present number of milliamps
(or Volts) per second and the required output currents (or voltages). An ADAM analog
output module may be configured for a specific slew rate.
