Product Overview

The 1756-DHRIO is a ControlLogix communication module used for Data Highway Plus and Remote I/O communication in legacy industrial control systems. It is commonly used when older PLC-5, SLC, or Remote I/O networks need to communicate with a ControlLogix platform during maintenance, retrofit, or phased migration projects.

Main Features

Communication module for ControlLogix systems
Supports Data Highway Plus and Remote I/O network integration
Useful for connecting legacy control networks with ControlLogix architecture
Suitable for factory maintenance, downtime recovery, and migration planning
Commonly used in legacy system bridge and scanner applications

Technical Specifications

Model	1756-DHRIO
Product Type	Communication Bridge / Scanner Module
Platform	ControlLogix
Network	Data Highway Plus / Remote I/O
Channel	2-Channel Communication Module
Application	Legacy Network Integration and Migration Support

Compatible System and Chassis Use

The 1756-DHRIO is used in ControlLogix chassis systems where communication with Data Highway Plus or Remote I/O networks is required. Final compatibility should be confirmed according to the installed controller, chassis, firmware level, network topology, and existing field wiring.

Industrial Applications

This module is used in factory automation systems, process plants, material handling lines, packaging equipment, and legacy production systems where existing DH+ or Remote I/O networks must remain operational during maintenance or migration.

Maintenance and Replacement Notes

The 1756-DHRIO is a high-value spare part for legacy system maintenance. It is often required when an older communication bridge fails or when a plant needs to keep existing Remote I/O infrastructure running while planning a gradual migration to newer network architecture.
