The EB401-10 supports 4-20 mA HART loop integration on compatible analog I\/O modules, allowing for standard field device communication without additional signal converters. Cold junction compensation (CJc) is applied internally for thermocouple measurements connected to the module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the EB401-10 hot-swappable within the node rack?\u003c\/strong\u003e\u003cbr\u003eA: No, the module must be powered down before insertion or removal to avoid backplane faults.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can multiple EB401-10 modules be installed in the same node unit?\u003c\/strong\u003e\u003cbr\u003eA: Yes, but each must occupy odd-numbered slots and be separated by a dummy module (ADCV01) for proper backplane termination.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the EB401-10 support firmware upgrades?\u003c\/strong\u003e\u003cbr\u003eA: Firmware can only be updated through the host controller interface; direct module flash is not supported.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eField Installation Guidelines\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eMount the EB401-10 module on a DIN rail, ensuring proper alignment with the node unit slots.\u003c\/li\u003e\n\u003cli\u003eVerify that the module occupies an odd-numbered slot; cover the adjacent right slot with a dummy module (ADCV01) to maintain bus integrity.\u003c\/li\u003e\n\u003cli\u003eConnect the ER Bus using standard YCB141 coaxial cabling; do not exceed 185 meters per segment.\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding and shield connection to minimize electromagnetic interference (EMI).\u003c\/li\u003e\n\u003cli\u003eMaintain ambient temperature between -10 degC and +60 degC; avoid direct exposure to condensation or dust accumulation.\u003c\/li\u003e\n\u003cli\u003eConfirm that input voltage is within 24 VDC ±20% before powering the module.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44152949506136,"sku":"EB401-10","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/EB401-10-2.jpg?v=1780023105","url":"https:\/\/www.industriaxplc.com\/products\/er-bus-interface-master-module-yokogawa-eb401-10","provider":"IndustriaX Limited","version":"1.0","type":"link"}
