This communication channel transfers digitized process input and output records, including 4-20 mA HART loop protocol dynamic variables and FOUNDATION Fieldbus telemetry. By supporting dual-redundant bus paths, the card maintains deterministic data transmission without message dropouts in the event of a single cable path fault.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum transmission distance supported by the EC401-10 S3 module?\u003c\/p\u003e\n\u003cp\u003eA: The module supports a maximum ESB bus cable transmission distance of 10 m between the Field Control Unit (FCU) and the destination Node Unit.\u003c\/p\u003e\n\u003cp\u003eQ: What data transfer rate is executed over the ESB bus interface?\u003c\/p\u003e\n\u003cp\u003eA: The EC401-10 S3 operates at a fixed communication speed of 128 Mbps across the ESB bus.\u003c\/p\u003e\n\u003cp\u003eQ: How does the EC401-10 S3 handle network communication redundancy?\u003c\/p\u003e\n\u003cp\u003eA: The module supports dual-redundant ESB bus configurations, allowing primary and secondary bus lines to maintain deterministic data flow if a signal path is disrupted.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eDe-energize system cabinet power before inserting or removing the EC401-10 S3 module from the Field Control Unit slot. Wear a grounded electrostatic discharge (ESD) wrist strap during handling to prevent physical damage to onboard semiconductor components. Mount the card vertically into its designated rack slot and tighten the top and bottom securing screws to establish chassis frame ground continuity. Ensure dedicated ESB bus cables are used, maintaining a total segment length not exceeding 10 m. Observe minimum bend radius limits for the communication cables and route them away from high-voltage AC lines to prevent electromagnetic coupling.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":53280324223285,"sku":"EC401-10 S3","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/EC401-10_c8e20d9e-056b-40cb-9ab6-65f0184233d7.jpg?v=1786670015","url":"https:\/\/www.5gplc.com\/products\/ec401-10-s3-yokogawa-esb-bus-coupler-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
