Complete optical isolation prevents ground loop currents from traversing remote cabinets, preserving channel-to-channel isolation on downstream analog input cards and maintaining cold junction compensation (CJC) stability on remote temperature transmitters.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What optical connector type and fiber configuration does the ANT502-53 require?\u003c\/p\u003e\n\u003cp\u003eA: The module utilizes standard duplex LC connectors conforming to IEC61754-20 and requires a 2-core optical fiber link operating at a 1.3 um wavelength.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module handle extended communication distances across field control networks?\u003c\/p\u003e\n\u003cp\u003eA: The module acts as an ESB bus repeater slave that converts electrical bus signals to optical signals, permitting noise-free transmission up to 5 km per optical hop.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the ANT502-53 into an assigned node slot or DIN-rail base assembly within the enclosure. Ensure that the cabinet grounding point connects directly to the local earth bus to dissipate electrostatic charges.\u003c\/p\u003e\n\u003cp\u003eWhen routing optical fiber cables, clean all LC connector end-faces prior to insertion. Respect the minimum bend radius specifications of the optical cable to prevent attenuation losses exceeding the permissible 0 to 10 dB margin. Secure 24 VDC power wiring to the primary supply terminals, keeping power conductors separated from optical paths to allow unobstructed access during routine maintenance.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43831912366170,"sku":"ANT502","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/7._c001ef04-b40d-454f-a996-535e6ea0e378.jpg?v=1786498851","url":"https:\/\/www.spareoil.com\/products\/ant502-53-yokogawa-5km-optical-esb-bus-repeater-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
