Full specifications and sourcing options are below.","salesMarkdown":"## Overview The 6ED10521CC080BA2 is a Siemens LOGO! 8.4 expansion module — 8 digital inputs, of which 4 can be used in analog mode (0 to 10 VDC), and 4 transistor outputs rated at 0.3 A switching current. This module extends the I/O capacity of a LOGO! 8.4 base unit. The 8 inputs accept standard 24 V DC digital signals; the first 4 channels can also read 0-10 VDC analog signals, eliminating the need for a separate analog input module on small applications. The 4 transistor outputs switch DC loads up to 0.3 A each — suitable for pilot lights, small contactors, or solid-state relays. An integrated real-time clock supports time-based logic, and the Ethernet interface allows remote programming and HMI connectivity. ## Applications LOGO! 8.4 expansion modules are used in small-scale automation — lighting control, HVAC zone management, pump sequencing, conveyor interlocks, and simple packaging machines. The mixed digital/analog input set suits applications that need a few analog sensors (temperature, pressure, level) alongside discrete signals, all within a compact DIN-rail footprint.","metaTitle":"Siemens 6ED10521CC080BA2 LOGO! 8.4 PLC Expansion Module, 8DI/4DO","metaDescription":"Siemens LOGO! 8.4 expansion module 6ED10521CC080BA2: 8 digital inputs (4 analog-capable 0-10 VDC), 4 transistor outputs 0.3 A, 24 V DC, DIN rail, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":[],"specifications":{"series":"LOGO! 8.4","has_mpn":"6ED10521CC080BA2","Min.
