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-processor is down, the module

will reset itself and send the safety value to the analog output therefore the

industry safety is guarantee. The safety value / power-up value can be set by

configuration software.
