Operating directly within a host PLC-3\/10 chassis, this hardware module interfaces local processor logic with remote I\/O chassis networks or Data Highway Plus (DH+) communication links. It manages high-speed serial data exchanges over up to four independent channels, ensuring reliable real-time scan cycles across distributed process configurations.\u003c\/p\u003e\n\u003ch3\u003eCommunication and Network Interface\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1775-SR5\u003c\/strong\u003e acts as a central communication link between the PLC-3\/10 processor and connected remote field devices. Supporting up to four I\/O channels, it accommodates up to 4,096 I\/O points in standard scanning modes. When configured to communicate over Data Highway Plus networks, one channel is dedicated to the peer-to-peer network link while the remaining three scan up to 3,072 remote I\/O points.\u003c\/p\u003e\n\u003ch3\u003ePower Requirements and Backplane Integration\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for single-slot installation within PLC-3\/10 chassis assemblies, the \u003cstrong\u003e1775-SR5\u003c\/strong\u003e draws its operational power directly from the system backplane. The module requires a stable supply of 5 VDC at 6 A to power its onboard processor, communication transceivers, and diagnostic circuitry.\u003c\/p\u003e\n\u003ch3\u003eSystem Redundancy and Replacement\u003c\/h3\u003e\n\u003cp\u003eIn redundant architecture setups, the \u003cstrong\u003e1775-SR5\u003c\/strong\u003e supports scanner backup operations when paired with identical hardware across primary and secondary PLC-3\/10 processors. Maintenance personnel replacing an older 1775-SR or 1775-S4A unit with a \u003cstrong\u003e1775-SR5\u003c\/strong\u003e must clear processor memory prior to installation and perform an auto-configuration procedure for each scanner channel to ensure proper communication setup.\u003c\/p\u003e\n\u003ch3\u003eTechnical Parameters\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1775-SR5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eCommunication Adapter Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible System\u003c\/td\u003e\n\u003ctd\u003ePLC-3\/10 Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eForm Factor\u003c\/td\u003e\n\u003ctd\u003eSingle Slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Power Requirements\u003c\/td\u003e\n\u003ctd\u003e5 VDC @ 6 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum I\/O Channels\u003c\/td\u003e\n\u003ctd\u003e4 Channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum I\/O Capacity\u003c\/td\u003e\n\u003ctd\u003e4,096 Points (3,072 Points when DH+ enabled)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e13.45 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What chassis architecture is compatible with the Allen-Bradley 1775-SR5 module?
