As systems evolve, the 1756-DHRIO serves as a critical bridge, facilitating communication between your established DH+ networks and other modules residing in a ControlLogix backplane. Furthermore, it functions as a robust RIO scanner, empowering your ControlLogix controller to efficiently exchange data with various remote RIO devices. While new 1756-DHRIO modules are no longer in production due to the age of DH+ technology, DD Parts Solution understands the ongoing need to support legacy systems. We often have access to meticulously inspected used or refurbished modules to ensure the continued operation of your existing architecture. It is important to acknowledge the inherent limitations of DH+ and consider strategic migration paths to contemporary technologies like Ethernet\/IP for new deployments or significant system enhancements. This module is an essential component for maintaining functionality in critical legacy operations.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy Network Integration:\u003c\/strong\u003e Provides essential connectivity to Data Highway Plus (DH+) networks, safeguarding existing system investments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote I\/O Scanning:\u003c\/strong\u003e Enables efficient data exchange and control with a wide array of Remote I\/O devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Channel Connectivity:\u003c\/strong\u003e Equipped with two independent channels for versatile DH+ network connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControlLogix Native:\u003c\/strong\u003e Designed for seamless and reliable integration within the Allen-Bradley ControlLogix chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Bridge Functionality:\u003c\/strong\u003e Acts as a crucial communication bridge between DH+ networks and the ControlLogix backplane.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSustained Operational Support:\u003c\/strong\u003e Ideal for maintaining critical processes in systems reliant on DH+ and RIO technologies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Performance:\u003c\/strong\u003e Continues to deliver consistent communication performance for legacy applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e DH+\/RIO Communication Module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e 1756-DHRIO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication Protocols:\u003c\/strong\u003e Data Highway Plus (DH+), Remote I\/O (RIO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDH+ Baud Rates:\u003c\/strong\u003e Supports 57.6 kbps, 115.2 kbps, and 230.4 kbps (optimally selected based on cable length and network topology).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e Standard DH+ connectors, typically 9-pin D-shell.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Slots:\u003c\/strong\u003e Occupies a single slot within a ControlLogix chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatus:\u003c\/strong\u003e Discontinued by manufacturer;
