3.12 ADAM-4051 16-channel Isolated Digital Input Module
The ADAM-4051 is a 16 channel Digital Input Module. It is built
with 2500V
DC
The main difference from other modules is that ADAM-4051 accepts
10 ~ 50V input voltage to fit various digital signals like 12 V, 24 V, and
48 V. Moreover, users can read the current status from the LED
indicators on the front panel.
