The 1791-32AO is a block I/O module. Block I/O modules are stand-alone I/O stations that is equipped with fixed 

I/O channels and a communication interface that support Remote I/O (RIO) communication. The 1791-32AO in 

particular is a Thirty-Two (32) channel block I/O module with each channel operating at a nominal input voltage of 

120VAC and operating voltage range of 79-132VAC along a frequency of 47-63Hz.
The input channels of the 1791-32AO are grouped into Four (4) groups with each group having Eight (8) channels each. 

Each input channel has a maximum Off-state voltage of 35V, minimum On-state current of 5 mA at 79V, 60 Hz and 

maximum On-state current of 12.3 mA @ 132VAC, 60 Hz. Each channels has switching delays of 1.0 ms for Off to 

On transition and maximum of 26 ms for On to Off transition.
The 1791-32AO comes with a single Remote I/O (RIO) communication port with isolation rating of 1250 VAC for I/O 

group to group isolation and 1250 VAC I/O group to logic isolation. Additionally, the Power supply to RIO port isolation 

is 500 VAC.
