For a duplex SB bus configuration, two repeat modules are required in each unit. Each module connects through a dedicated SB bus T-joint and cable.\u003c\/p\u003e\n\u003cp\u003eThe module has a specific base-module requirement: it is designed for the NFBU200 long base module. It cannot be installed on the N2BU051, NFBU050 short base module, or N2BU030 compact base module. This distinction should be checked before ordering a replacement or planning a system modification.\u003c\/p\u003e\n\u003cp\u003eYokogawa specifies a maximum of two extension units, or three units when the control unit is included. The 8 m transmission-distance limit applies to each SB bus segment rather than the total system cable length.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the NFSB100-S50\/SBT01 support hot swapping?\u003c\/p\u003e\n\u003cp\u003eA: Yes. Hot swapping is supported. However, this capability should not be confused with duplex operation, which requires two NFSB100 modules per unit.\u003c\/p\u003e\n\u003cp\u003eQ: What is required for a duplex SB bus configuration?\u003c\/p\u003e\n\u003cp\u003eA: Install two NFSB100 repeat modules in each unit using the applicable base-module arrangement, dedicated T-joints, and SB bus cables. The duplex configuration uses separate repeat modules for the two bus paths.\u003c\/p\u003e\n\u003cp\u003eQ: Can the NFSB100-S50\/SBT01 be installed on an NFBU050 base module?\u003c\/p\u003e\n\u003cp\u003eA: No. The NFSB100 is specified for the NFBU200 long base module and is not compatible with the NFBU050 short or N2BU030 compact base modules.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":68436570374386,"sku":"NFSB100-S50\/SBT01","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/NFSB100-S50SBT012.jpg?v=1793778656","url":"https:\/\/www.petrospare.com\/products\/yokogawa-nfsb100-s50-sbt01-sb-bus-repeater-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
