The Allen-Bradley 1791-32AO AC Block I/O Module is a standalone I/O station with a communication interface that supports Remote I/O communication, and fixed I/O channels. Block I/O modules use their own programmable controller interface, I/O connections, power supply, and signal conditioning circuitry. \
The 32AO Block I/O is compatible with PLC-2, PLC-3, PLC-5/250, and PLC-5 programmable controllers, as well as SLC 5/02 modular controllers.
