    1. 2. Overview of NuDAM-6021 What is NuDAM-6021 ? ND-6021 is an analog signal output module. It receives the digital command from host computer through RS-485 network. The format of the digital value can be engineering units, hexdecimal format or percentage of full-scale range(FSR).
  • Page 6 The analog output can be readback through the module‘s ADC. which can monitor the ’real‘ output of the device. The host can check the digital command and the real output to avoid short circuits. The slew rate of the output signal is also controllable by software. Features of NuDAM-6021 •...
