1. 1. About the NuDAM Analog Output Modules
The NuDAM provides an analog output modules which can
convert the digital command to analog. The basic features of
each module are shown here.
• NuDAM-6021 : analog signal output module with safety
functions
• NuDAM-6024 : 4 channel analog output module
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). A microprocessor
is used to convert the digital command to digital value to send to
DAC. The DAC converts the digital value into analog form. The
analog output can be either voltage or current output.
The ND-6021 is designed for safety. It provides many safety
functions such as isolation, watchdog, and power on safe value.
The opto-isolators provide 5000Vrms isolation voltage to isolate
the digital section and the remote controlled analog equipments.
The damage of power surges is avoided.
Another safety fucntion is the watchdog. Whenever the host is
loss contact with the remoted NuDAM module, or the micro-
processor is down, the module will reset itself and send the safety
value to the analog output therefore the industry safety is
