1.2 Overview of NuDAM-6050

1.2.1 What is NuDAM-6050?

NuDAM-6050 is a digital input and output module. The digital input channels

can monitor active TTL signals, and sense passive switch on/off signal

because of the internal pull high resistors. The convenient open collector

output channels can sink up to 50 mA current. Combining with the relay

devices, it is possible to control the high power devices by programming

output channel of the NuDAM-6050.

1.2.2 Features of NuDAM-6050

♦ 7 bits digital input

♦ 8 bits open collector digital output

♦ Programmable host watchdog timer for host failure protection

♦ Internal watchdog timer for device failure protection

♦ Easy programming by software

♦ Easy installation and wiring
