模拟量输出模块接收到主机的请求信号后，就将数据通过RS-485网络按照所需的格式发送出去。数据的格式有工程单位、二进制补码、满量程的百分比（FSR），取决于模块的配置。由于独立于DAC(数模转换器),因此可以为微处理器提供真正的模拟量输出信号回读功能。如果ADC所测的数据与要输出的数据不同，则表示所要输出的模拟量正在转换。这样可以很容易地检测出由于错误连接或非期望负载所引起的输出故障。模拟量输出模块提供了单通道的电压或电流输出。它们提供3000VDC对地回路的隔离保护，确保您的仪器免于振动和浪涌的危害。

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.
