Configured for physical layer signal transformation across fiber-optic interconnects, this personality module establishes deterministic point-to-point data links up to 3.7 km. The unit interfaces directly with Ovation controller base assemblies to handle fiber transceiver routing and hardware signal conversion without introducing software transmission latency.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1C31181\u003c\/strong\u003e: Base electronic assembly part number denoting the Ovation physical module type.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eG03\u003c\/strong\u003e: Group variant identifier defining specific optical transceiver power, wavelength, and 3.7 km range rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaster\u003c\/strong\u003e: Controller interface role for master node synchronization across the local network.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePMOD\u003c\/strong\u003e: Personality Module architecture designation for direct controller base mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2N\u003c\/strong\u003e: Dual-node \/ redundant physical fiber channel configuration specifier.\u003c\/li\u003e\n\u003c\/ul\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\u003e1C31181G03\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\u003e0.85 lbs (0.39 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Ovation PMOD form factor\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\u003eLogic-level backplane supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Transmission Distance\u003c\/td\u003e\n\u003ctd\u003eUp to 3.7 km\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Interface\u003c\/td\u003e\n\u003ctd\u003eFiber-optic dual-node (2N) attachment interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation and Optical Signal Protocol\u003c\/h3\u003e\n\u003cp\u003eThe 1C31181G03 module incorporates galvanic and optical channel-to-channel isolation between internal digital logic rails and field fiber connections. This topology suppresses ground loop transients and electromagnetic noise propagation over extended 3.7 km link distances. Transceiver driver circuits process light pulses through dedicated optical channels, maintaining 4-20 mA HART loop protocol pass-through integrity and deterministic update intervals across the distributed Ovation control network.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1C31181G03 module be swapped under field power without interrupting the controller base?\u003c\/p\u003e\n\u003cp\u003eA: Hot-swapping must comply with standard Ovation controller base restrictions; field fiber connectors and power rails must be isolated or disengaged per site safety procedures prior to module extraction.\u003c\/p\u003e\n\u003cp\u003eQ: What physical cable type is required for the 3.7 km transmission distance specified by the G03 variant?\u003c\/p\u003e\n\u003cp\u003eA: The unit requires multi-mode or single-mode fiber cables matching the specific optical wavelength and launch power constraints engineered into the G03 physical transceiver assembly.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eIsolate system power and disconnect fiber-optic LC\/ST connectors prior to inserting or removing the module.\u003c\/li\u003e\n\u003cli\u003eAlign the PMOD rear pin headers with the Ovation controller base slot and press firmly until fully seated.\u003c\/li\u003e\n\u003cli\u003eObserve minimum fiber optic bend radius rules (typically 30 mm minimum) when routing cables within the enclosure.\u003c\/li\u003e\n\u003cli\u003eClean all optical fiber end-faces with lint-free isopropyl wipes before mating to prevent signal attenuation.\u003c\/li\u003e\n\u003cli\u003eSecure all panel mounting hardware to ensure proper chassis earth ground bonding through the DIN assembly or backplate.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":66749795795059,"sku":"1C31181G03","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1C31181G03_Cocoai.jpg?v=1790754501","url":"https:\/\/www.dcssupplier.com\/ar\/products\/emerson-1c31181g03-master-attachment-unit-pmod","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
