Adam-4051 16-Channel Isolated Digital Input Module - Advantech Adam 4000 Series User Manual

3.13 ADAM-4051 16-channel Isolated Digital Input
Module
The ADAM-4051 is a 16 channel Digital Input Module. It is built with 2500VDC optical
isolation, and it is suitable for critical applications. The main difference from other
modules is that ADAM-4051 accepts 10 ~ 50V input voltage to fit various digital sig-
nals like 12 V, 24 V, and 48 V. Moreover, users can read the current status from the
LED indicators on the front panel.
