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.
