Panel Fit and I/O Count for a Compact Controller
The Siemens 6ED1052-1MD00-0BA8 is a LOGO! 12/24RCE logic module that snaps onto a 35 mm DIN rail, occupying 4 spacing units (71.5 mm wide). It integrates the power supply, I/O, display, and Ethernet in one 90 mm x 60 mm footprint — a single unit that replaces a handful of separate components in a small control cabinet. It provides 8 digital inputs, of which 4 can be configured as analog inputs (0 to 10 V), and 4 relay outputs rated 10 A resistive / 3 A inductive. That I/O mix suits small machine control, lighting, or HVAC applications where you need a few analog signals without adding an expansion module.
Supply Voltage and Operating Range
The module accepts 12 V DC or 24 V DC supply, with a permissible range of 10.8 V to 28.8 V DC. It includes a 480-hour power reserve, so the program and retentive data survive a line drop without a separate battery. Rated for 0 °C to 55 °C ambient (LOGO! 8 FS04 and higher extend the low end to -20 °C). The unit carries CE, UL, CSA, FM, and marine approvals, making it straightforward to spec into panels destined for North America, Europe, or shipboard use.
