1. 3. Overview of NuDAM-6024
What is NuDAM-6024 ?
ND-6024 is a 4 channel bipolar analog signal output module. It
receives the digital command from host computer through RS-
485 network. 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 ND-6024 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-
