1.6 Overview of NuDAM-6056
1.6.1 What is NuDAM-6056 ?
NuDAM-6056 provides 15 isolated digital output channels. All of the output
channels are common ground type and one of them is use the same pin with
default (use jumper to choose). The isolation voltage is up to 5000 Vrms. It
is suitable to use NuDAM-6056 in industrial environment with the dangerous
of high voltage electric shock.
1.6.2 Features of NuDAM-6056
♦ 15 bits digital open collector output with isolation protection and
common ground
♦ 5000 Vrms isolation voltage
♦ Programmable host watchdog timer for host failure protection
♦ Internal watchdog timer for device failure protection
♦ Easy programming by software
♦ Easy installation and wiring
