Product Description P/N: 1756-RIO
Description
The Allen-Bradley 1756-RIO is a Remote I/O communication module designed for ControlLogix systems, enabling seamless integration with legacy RIO networks. It operates as either a scanner or an adapter and supports block transfer, analog, specialty, and digital data exchange. With one RIO port and compatibility with up to 32 physical racks, the 1756-RIO provides a reliable link between modern ControlLogix controllers and classic RIO-based systems.

Information About 1756-RIO
The 1756-RIO is part of the ControlLogix communication family, built to connect ControlLogix processors to Remote I/O networks using a single-slot configuration. It supports all remote I/O baud rates, partial rack addressing, and up to 32 adapters across its single RIO channel. The module’s design allows for independent DH+/RIO-style communication without the need for message instructions, automatically handling block transfers and scheduled I/O. Common applications include system modernization, SCADA integration, and interfacing ControlLogix processors with existing PLC-5 or SLC-based RIO infrastructures.
Key Features:
- Scanner or Adapter Operation: Flexible network role for integration with legacy RIO systems.
- Single RIO Channel: Supports up to 32 physical adapters or any rack-size combination.
- Block Transfer Support: Handles analog, specialty, and digital data without message commands.
- ControlLogix Chassis Compatible: Installs in any slot of 1756-A4/A7/A10/A13/A17 chassis.
- Wide Power Supply Support: Works with both standard and redundant 1756-series power supplies.
- Network Reliability: Provides 50 V continuous isolation from RIO lines to backplane.
- Scheduled I/O Capability: Supports up to 10 scheduled connections.
- Legacy Cable Support: Uses 1771-CD or Belden 9463 “Blue Hose” for RIO connectivity.
The 1756-RIO delivers the reliability and precision required for bridging ControlLogix systems with Remote I/O industrial networks.
