Remote I/O and Control Platform Communication
The 1791-OA16 uses Allen-Bradley Remote I/O communication architecture for discrete output control and integrates with PLC controller platforms through an RIO adapter interface. The module supports industrial control network configuration with controller-side addressing and remote output data exchange.
The module architecture supports I/O density scaling by combining 16 AC output channels into a single Block I/O assembly. Firmware flash compatibility and controller configuration parameters must be verified when integrating the module into existing PLC systems.
The output circuitry provides two isolated output groups, each containing eight channels. The AC switching outputs are designed for connection to field actuators and discrete loads within the specified voltage and current ranges.
Frequently Asked Questions
Q: How many output channels are available on the 1791-OA16?

A: The module is specified for use with PLC-2, PLC-3, PLC-5/250, PLC-5 family controllers, and SLC 5/02 modular controllers.
Field Installation Guidelines
Install the 1791-OA16 according to the mechanical requirements of the Block I/O mounting environment. Verify AC supply wiring, output terminal assignments, and RIO communication connections before applying power.
Route RIO communication cables separately from high-voltage AC wiring to reduce electrical interference. Use the specified communication cable type and install terminating resistors according to the network configuration requirements.
Before commissioning, verify controller addressing, RIO adapter configuration, and each output channel response under controlled test conditions. Confirm connected field loads remain within the specified output voltage and current limits.
