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.
