The Allen-Bradley 1791-OA16 Guard I/O AC Block I/O Module is an output module with 16 AC output channels, providing signal voltages of 20 to 132VAC with frequency of 47 to 63Hz.

SLC 500 controllers communicate with the block I/O using an I/O scanner module. Note that this block I/O module is not compatible with the 1747-DSN Distributed I/O Scanner Module.

A termination resistor must be installed on the last block in a series.
