When configured with HART-enabled FIO modules, the backplane facilitates digital communication superimposed on the analog current loop. Channel-to-channel isolation is maintained within the connected FIO modules to prevent ground loop interference between field devices. The integrated optical repeater converts electrical ESB bus signals to optical signals, ensuring data integrity over extended distances without electromagnetic susceptibility.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the ANB11D support hot-swapping of FIO modules?\u003c\/p\u003e\n\u003cp\u003eA: FIO module hot-swapping capability depends on the specific module type installed; refer to the individual FIO module manual for live replacement restrictions. Power supply modules in the dual-redundant configuration can typically be replaced online.\u003c\/p\u003e\n\u003cp\u003eQ: What is the function of the \/BU2B option?\u003c\/p\u003e\n\u003cp\u003eA: The \/BU2B designates a connector unit with an integrated ESB bus terminator. This eliminates the requirement for external terminating resistors at the physical end of the ESB bus segment.\u003c\/p\u003e\n\u003cp\u003eQ: Are there any cooling requirements for this unit?\u003c\/p\u003e\n\u003cp\u003eA: Cooling is achieved via natural air convection. Ensure adequate clearance around the ventilation slots in the 19-inch rack to maintain ambient temperature limits.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the unit in a standard 19-inch rack using M5 screws. Ensure the functional grounding terminal (M4 screw) is connected to the panel's ground bus with minimal impedance. When routing the 5 km optical fiber, avoid tight bending radii exceeding the cable manufacturer's specifications to prevent signal attenuation. For ESD protection, ensure all field wiring to the FIO modules is disconnected before installation or removal of the node unit. Verify the power supply voltage matches the 220-240 V AC rating prior to energizing the unit.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44203006099544,"sku":"ANB11D-225\/BU2B","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/ANB11D-225BU2B-2.jpg?v=1780885988","url":"https:\/\/www.industriaxplc.com\/id\/products\/anb11d-225-bu2b-yokogawa-dual-redundant-esb-bus-optical-repeater","provider":"IndustriaX Limited","version":"1.0","type":"link"}
