The Allen Bradley 1791-IOBA serves as a Remote I/O (RIO) block module, designed for flexibility in industrial environments. It consists of 16 total I/O points distributed equally, featuring 8 inputs along with 8 outputs. The module employs the Universal Remote I/O (RIO) network protocol for communication.

Powered within a range of 20.5 to 27.6 volts DC, this module can adapt to various setups. Addressing is straightforward, accomplished through rotary switches that allow configuration of the rack number and associated I/O group. The input types on the 1791-IOBA support both sinking and sourcing, while the output type is configured as sourcing (PNP) at a typical voltage of 24 volts DC.

An important aspect of this module is its opto-isolated I/O circuitry, which provides protections and ensures reliable performance in different scenarios. Users benefit from removable terminal strips for easy wiring, which can be mounted either through panel screws or on a DIN rail, allowing for efficient integration into existing setups.
