Configured for managing synchronous multi-drop terminal connections, the card translates high-level processor commands into differential electrical signals to govern external instrumentation lines. It acts as a dedicated communications bus interface on the controller backplane, executing packet serialization, verifying protocol syntax, and managing traffic flow across localized network nodes.\u003c\/p\u003e\n\u003ch3\u003eHardware 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\u003e1C31166G02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eEmerson\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.45 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e45 x 130 x 160 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e4.5 W maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eLC EMOD Serial Link Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eRS-485, 4-wire configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefault Protocol\u003c\/td\u003e\n\u003ctd\u003eModbus RTU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardware Compatibility\u003c\/td\u003e\n\u003ctd\u003eEMOD and PMOD slot architectures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHost CPU Platform\u003c\/td\u003e\n\u003ctd\u003eR1120 execution environment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Configuration\u003c\/td\u003e\n\u003ctd\u003eDual-channel track matching support\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHot-Swap Capability\u003c\/td\u003e\n\u003ctd\u003eSupported under active rack power conditions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eIndustrial Control Systems and Network Architecture\u003c\/h3\u003e\n\u003cp\u003eThe module interfaces directly with industrial automation networks running deterministic serial communications. It utilizes integrated logic boundaries to maintain stable operation under continuous processing loads while executing data exchanges over the backplane bus communication velocity networks. This high-density transaction pipeline is sustained via matching firmware flash compatibility structures on the host R1120 CPU platform, which allows the serial link interface to pass physical input and output variables to adjacent racks without causing timing drift or bus synchronization faults.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is it permissible to extract the 1C31166G02 from an operational backplane without turning off the rack power supply?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The hardware is designed with hot-swappable circuit boundaries that allow live extraction and insertion. Replacing the module during active operations will not corrupt the common internal backplane bus or interfere with adjacent processing slots, provided the redundant communication line is fully synchronized.\u003c\/p\u003e\n\u003cp\u003eQ: Can this serial link card be used to map data from non-Emerson programmable logic controllers?\u003c\/p\u003e\n\u003cp\u003eA: Yes. Because the interface is hard-coded to support the standard Modbus RTU protocol over a physical 4-wire RS-485 boundary, it can communicate directly with third-party instruments, protection relays, and PLCs that match these exact electrical and software specifications.\u003c\/p\u003e\n\u003cp\u003eQ: How does the lifecycle status affect the configuration and integration of this module in legacy systems?\u003c\/p\u003e\n\u003cp\u003eA: Although this model has been officially discontinued by the manufacturer, the hardware remains backward-compatible with legacy Ovation DCS chassis configurations. It fits directly into existing EMOD and PMOD architectures without requiring changes to the base system software.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify that the slot alignment pins on the backplane match the guide rails of the card before inserting the module into the rack.\u003c\/li\u003e\n\u003cli\u003eTighten all faceplate retaining screws to ensure continuous ground continuity between the module frame and the enclosure earth bus.\u003c\/li\u003e\n\u003cli\u003eTerminate the 4-wire RS-485 line with standard end-of-line resistors to suppress signal reflections and electrical noise on long cable runs.\u003c\/li\u003e\n\u003cli\u003eRoute all serial communication cables through dedicated low-voltage wireways, keeping them separate from high-voltage AC distribution tracks.\u003c\/li\u003e\n\u003cli\u003eCheck that the external shielding braid of the RS-485 link is grounded at a single point to prevent ground loops from disrupting data transmission.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":43881523085411,"sku":"1C31166G02","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/17_545ecc42-17cb-49e9-a394-1a94024de21d.jpg?v=1765328338","url":"https:\/\/www.autocontrolglobal.com\/products\/1c31166g02-emerson-ovation-serial-link-controller-new-original-stock","provider":"AutoControl Global","version":"1.0","type":"link"}
