RS485, TCP/IP, UDP, S7 routing, 244 byte I/O, galvanic isolation. cULus, CE.","salesMarkdown":"## What this SFB interface module brings to a control cabinet The 6ES7154-8AB00-0AB0 Siemens SFB interface module connects a fieldbus network to a distributed station and supports CFC, FBD, LAD, SCL, STL, GRAPH, and HiGraph®. Its 244-byte I/O process image handles medium loads with 16 slots for mixed modules. ## Fieldbus and Ethernet – dual-path connectivity The module provides a fieldbus interface with TCP/IP and UDP Ethernet but no IRT for real-time cycles. S7 routing allows gateway functionality between subnets. ## Installation and electrical isolation Galvanic isolation between the bus and I/O circuits stops ground loops that sneak in from nearby motor drives or furnace radiant heat – a common failure in steel-mill cabinets. The module takes 135 mm width, 130 mm height, and 65 mm depth (60 mm without the RJ45 cover). That depth figure includes the cover for the RJ45 socket; if you use the connector with cover, clearance is 65 mm behind the panel. ## Sourcing note No lifecycle status is published for this order code. We source it against an RFQ – if you have a line-down need or a BOM slot to fill, send the request with your target quantity and ship-by date. The compliance package (CE mark, cULus) covers most industrial installations.","metaTitle":"Siemens 6ES7154-8AB00-0AB0 SFB Interface, CFC/FBD/SCL, cULus","metaDescription":"Interface module supporting CFC, FBD, LAD, SCL, STL, GRAPH.
