Dedicated filtering components attenuate high-frequency electromagnetic interference across the 128 Mbps data line, ensuring error-free frame delivery for process variables originating from field devices operating on 4-20 mA HART loop protocol instruments. Integrated cold junction compensation (CJC) processing references from peripheral I\/O cards are relayed across the bus without latency degradation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum allowable distance for the ESB bus network connected through the EC401-10 S3?\u003c\/p\u003e\n\u003cp\u003eA: The total transmission cable distance between the FCU and the furthest connected node unit must not exceed 10 m.\u003c\/p\u003e\n\u003cp\u003eQ: How many node units can be connected to a single EC401-10 S3 module?\u003c\/p\u003e\n\u003cp\u003eA: A maximum of 9 node units can be connected in daisy-chain topology per module pair.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eSeat the EC401-10 S3 module into the designated coupler slot of the Field Control Unit chassis, ensuring complete connector mating before securing the top and bottom mounting screws to 0.5 Nm torque. Connect specified dedicated ESB bus cables between the module interface port and the node expansion units, observing the 10 m total length restriction. Maintain signal wiring separation of at least 150 mm from AC power distribution lines. Ensure cabinet operating ambient temperatures remain strictly within the -10 to 60 deg C operational range.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":48759124820158,"sku":"EC401-10 S3","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/AAI543-S50_3_b28e19dc-6ebc-4232-8809-17db60e48483.jpg?v=1787125687","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-ec401-10-s3-esb-bus-coupler-modules","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
