The hardware operates as a slave-side terminal device that receives differential optical data vectors from a matching master repeater unit via dual-core fiber optic lines and translates the data stream back into electrical bus signals. This function enables deterministic real-time synchronization across localized and distant input\/output processing racks without modifying data packet structures.\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\u003eSNT501-13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e32.8 x 142.5 x 130 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e2.5 W maximum (0.5 A at 5 VDC internal logic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eOptical ESB Bus Repeater (Slave side)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmission Medium\u003c\/td\u003e\n\u003ctd\u003eDual-core fiber optic cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Ports\u003c\/td\u003e\n\u003ctd\u003eOPT IN\/OUT (Optical), CN1 (Electrical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePairing Requirement\u003c\/td\u003e\n\u003ctd\u003eSNT401 Master Repeater Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmission Distance\u003c\/td\u003e\n\u003ctd\u003e500 m to 5 km (up to 10 km under specific Vnet\/IP matrices)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Topology\u003c\/td\u003e\n\u003ctd\u003eStar or chain configurations (maximum 2 stages)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStyle Variant\u003c\/td\u003e\n\u003ctd\u003eS1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control Loops and Optical Field Configurations\u003c\/h3\u003e\n\u003cp\u003eThe interface architecture utilizes physical fiber connections to execute absolute galvanic isolation between distinct chassis segments. By translating standard communication frames into light pulses, the system bypasses the grounding offset risks associated with traditional copper lines, ensuring total stability for parallel 4-20 mA HART loop protocol paths running nearby. The optical components are completely isolated from electromagnetic interference (EMI), suppressing cross-talk and baseline voltage fluctuations. This ensures that adjacent analog modules, requiring precise cold junction compensation (CJC) algorithms or individual channel-to-channel isolation, process process inputs without encountering induced noise or grounding loop errors.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the system architectural requirements regarding module pairing for this device?\u003c\/p\u003e\n\u003cp\u003eA: The slave module cannot operate in isolation or communicate directly with standard media converters. It requires a dedicated peer link with an SNT401 Master Repeater Module to complete the optical-to-electrical bus translation loop.\u003c\/p\u003e\n\u003cp\u003eQ: Does the module support physical hot-swap installation procedures during runtime?\u003c\/p\u003e\n\u003cp\u003eA: No. Removing or inserting the module while the system chassis is energized can cause unexpected signal interruption or transient faults on the local ESB bus. The rack power supply must be isolated prior to performing any module replacement procedures.\u003c\/p\u003e\n\u003cp\u003eQ: How do fiber configuration variations affect the maximum communication range?\u003c\/p\u003e\n\u003cp\u003eA: Standard transmission ranges span from 500 m to 5 km using multi-mode fiber infrastructure. Under specific system configurations utilizing Vnet\/IP R1.03 or higher, the maximum operational limit extends up to 10 km, provided that insertion losses remain within specified limits.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDisconnect all primary power tracking paths to the local ESB interface chassis before positioning the card into its designated slot.\u003c\/li\u003e\n\u003cli\u003eClean all optical fiber faces with specialized lint-free cleaning instruments before coupling the dual-core lines to the OPT IN\/OUT ports.\u003c\/li\u003e\n\u003cli\u003eObserve strict minimum bending radius tolerances when routing the fiber optic cables inside the marshalling enclosure to prevent signal attenuation or physical fiber fracture.\u003c\/li\u003e\n\u003cli\u003eMaintain complete separation between copper field distribution wiring and optical networks to optimize the advantages of complete galvanic isolation.\u003c\/li\u003e\n\u003cli\u003eConfirm that the mechanical locking levers are completely engaged with the chassis framework to ensure the module is grounded through the system backplane tracks.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44220721954915,"sku":"SNT501-13","price":360.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/324._4d85318a-66ae-43c4-832c-fa699ff19fa2.jpg?v=1780040719","url":"https:\/\/www.autocontrolglobal.com\/products\/snt501-13-yokogawa-optical-bus-repeater-new-original-stock","provider":"AutoControl Global","version":"1.0","type":"link"}
