It establishes high-speed, deterministic data communication between local CPU backplanes and remote field drops over S908 coaxial networks. Featuring dual coaxial communication channels and an integrated communication status array, the \u003cstrong\u003eAS-J890-102\u003c\/strong\u003e delivers physical media redundancy and immediate diagnostic monitoring to safeguard network health.\u003c\/p\u003e\n\u003ch3\u003eRedundant Coaxial Communication Architecture\u003c\/h3\u003e\n\u003cp\u003eOperating over standard S908 network infrastructure at a 1.544 Mbps data transfer rate, the \u003cstrong\u003eAS-J890-102\u003c\/strong\u003e functions as a primary interface node for remote I\/O drops. Its dual-channel design utilizes two front-facing F-connector coaxial ports. This allows setup in redundant-cable topologies, ensuring continuous data transmission to and from the main processor rack even if one coaxial cable run experiences an open or short circuit.\u003c\/p\u003e\n\u003cp\u003eCompared to standard single-channel remote interface units, the dual-channel configuration continuously manages primary and secondary signal lines. Address selection for each remote drop is accomplished using onboard configuration rotary or DIP switches before inserting the card into the rack slot.\u003c\/p\u003e\n\u003ch3\u003eIntegrated Status LED Array and System Monitoring\u003c\/h3\u003e\n\u003cp\u003eThe module features an integrated communication status array on the front panel. This dedicated LED matrix provides visual feedback covering system readiness, active channel communication, and transmission errors across both channels.\u003c\/p\u003e\n\u003cp\u003eBy providing clear hardware-level indicators, maintenance personnel can assess network health, verify link synchronization, and isolate drop faults on site without connecting external programming software. The unit inserts directly into standard Modicon 800 Series primary housings, receiving operational power through the internal backplane bus.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\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\u003eAS-J890-102\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric \/ Modicon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRemote I\/O Processor Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eModicon 800 Series \/ 984 System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eS908 Remote I\/O (RIO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Transmission Rate\u003c\/td\u003e\n\u003ctd\u003e1.544 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Configuration\u003c\/td\u003e\n\u003ctd\u003eDual Channel (Redundant F-Connector Coaxial Ports)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiagnostic Display\u003c\/td\u003e\n\u003ctd\u003eFront-Panel Communication Status Array (LEDs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Drop Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 1024 Discrete Inputs \/ 1024 Discrete Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Form Factor\u003c\/td\u003e\n\u003ctd\u003eModicon 800 Series Rack Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUnit Weight\u003c\/td\u003e\n\u003ctd\u003e3.84 lbs (1.74 kg)\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 is the main distinction between the AS-J890-002 and the AS-J890-102 modules?\u003c\/p\u003e\n\u003cp\u003eA: While both are dual-channel remote I\/O processor modules for Modicon 800 Series drops, the \u003cstrong\u003eAS-J890-102\u003c\/strong\u003e includes an expanded communication status array on the front panel for advanced visual link diagnostics and network health monitoring.\u003c\/p\u003e\n\u003cp\u003eQ: Can the AS-J890-102 operate with only one coaxial cable connected?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module can operate on a single coaxial connection.
