Fully compatible with SS8401 series ESB slave modules, the card features internal galvanic isolation to eliminate ground loop noise across distributed bus segments. The high-speed serial links support redundant bus topologies, preserving telemetry throughput and transparent signal routing for connected 4-20 mA HART loop protocol transmitters and process I\/O channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum segment distance supported by the EB402-10 module for ESB cabling?\u003c\/p\u003e\n\u003cp\u003eA: The module supports a maximum physical cable length of up to 10 meters per ESB bus segment using standard shielded twisted-pair cabling.\u003c\/p\u003e\n\u003cp\u003eQ: Does the EB402-10 support dual-redundant ESB bus configurations?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the EB402-10 can be installed in redundant pairs within the FCU chassis to provide uninterrupted bus failover protection.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize the host Field Control Unit rack power before installing or removing the EB402-10 module.\u003c\/li\u003e\n\u003cli\u003eAlign the module card edges with the designated FCU coupler slot card guides and slide the assembly in until the rear edge connector seats fully into the backplane.\u003c\/li\u003e\n\u003cli\u003eFasten the front top and bottom retaining screws to secure the chassis connection and ensure proper shield grounding.\u003c\/li\u003e\n\u003cli\u003eConnect the shielded twisted-pair ESB bus cable between the master EB402-10 port and the input port of the remote slave node unit, ensuring segment runs do not exceed 10 meters.\u003c\/li\u003e\n\u003cli\u003eApply approved line-terminating resistors at the final slave node unit on the ESB bus run to prevent signal reflections across the 128 Mbps communication line.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":52626084495640,"sku":"EB402-10","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/NFAF135-S50_3_ff26e360-998b-44e1-9ef7-adda245c93cd.jpg?v=1788773481","url":"https:\/\/www.innoplcsync.com\/products\/yokogawa-eb402-10-esb-bus-coupler-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
