Siemens 6ED1052-1HB08-0BA2 is the LOGO! 24RCE base module for 24 V AC/DC control power. It provides eight digital inputs, four relay outputs, a local display and keys, and the Ethernet connection used by the LOGO! 8.4 engineering and communication functions.
In a machine circuit, Siemens 6ED1052-1HB08-0BA2 reads the eight 24 V field states into the user program and switches externally supplied loads through its four relay contacts. Because the contact side is separate from the input supply, the load voltage, protection and return path must be documented independently.
Expansion and network operation extend Siemens 6ED1052-1HB08-0BA2 beyond its base I/O. The exact expansion order, IP settings, program version and local-display pages belong to the device record and should be retained together during commissioning or replacement.
