Configured as a fiber-optic slave module for N-IO and FIO subsystems, this rack-mounted device provides direct physical execution by converting optical data streams back into parallel electrical ESB bus signals over a maximum transmission span of 5 km.\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\u003eANT502-50\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\u003eApprox. 0.25 kg (Shipping Weight: 1 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard FIO\/N-IO node interface card profile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C standard industrial cabinet range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eSourced via internal node backplane logic rails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCore Product Type\u003c\/td\u003e\n\u003ctd\u003eOptical ESB Bus Repeater Slave Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Fiber Distance\u003c\/td\u003e\n\u003ctd\u003e5 km\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Bus Compatibility\u003c\/td\u003e\n\u003ctd\u003eN-IO and FIO Node Extension Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Medium\u003c\/td\u003e\n\u003ctd\u003eDual fiber-optic cable interface ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity and System Integration\u003c\/h3\u003e\n\u003cp\u003eThe ANT502-50 manages synchronous optical signal conversion to maintain baseline backplane bus communication velocity metrics, validating high-speed FIO\/N-IO data transmission across extended distances without packet collision or propagation frame lag. By executing optical-to-electrical signal serialization directly on its localized media access plane, the hardware permits real-time physical I\/O density scaling routines across remote control nodes located up to 5 km from the master Field Control Unit (FCU). The internal transceiver arrays retain complete firmware flash compatibility with upstream CENTUM engineering platforms, allowing continuous monitoring of fiber link status and optical attenuation metrics straight to the primary system tracking registers.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What operational status occurs if the optical fiber signal drops below the required reception threshold on the ANT502 module?\u003c\/p\u003e\n\u003cp\u003eA: The onboard optical diagnostics immediately detect the signal attenuation or loss of light. The module sets a data link error bit, alerts the redundant path if configured, and flags the remote node state as offline within the master controller's diagnostic subroutines.\u003c\/p\u003e\n\u003cp\u003eQ: Can the ANT502 slave repeater be hot-swapped while the remote N-IO or FIO node is actively processing live process data loops?\u003c\/p\u003e\n\u003cp\u003eA: No, pulling a non-redundant slave repeater while under power instantly interrupts the ESB bus extension link. This loss of communication forces all connected remote analog and digital I\/O modules into their pre-programmed safe or unpowered default states.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":45054357995635,"sku":"ANT502-50","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-05-18_13-44-38_5c650228-5c6e-4bcf-80c5-f66eef4b5f97.png?v=1780019549","url":"https:\/\/www.dcssupplier.com\/products\/yokogawa-ant502-50-optical-esb-bus-repeater-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
