You can specify slew rates and start up currents through the configu-
ration software. The analog output can also be configured as current
or voltage through the software utility. The module protects your
equipment from ground loops and power surges by providing opto-
isolation of the D/A output and transformer based isolation up to 500
V .
DC
The slew rate is defined as the slope indicated the ascending or
descending rate per second of the analog output from the present to
the required.
