Panel fit and I/O count for small automation tasks
The Siemens 6ED1052-2CC01-0BA6 is a LOGO! 24CO logic module — a compact controller without a display, designed for DIN-rail mounting at 4 spacing units wide. It runs on 24 V DC (permissible range 20.4 V to 28.8 V) and carries 8 digital inputs, of which 4 can be configured for analog 0 to 10 V signals, plus 4 transistor outputs rated 0.3 A per channel at signal "1" up to 55 °C. The 200-block memory and integrated real-time clock make it suitable for standalone or modularly expanded control in small machines, conveyors, or building-automation panels.
The 8 digital inputs (4 usable as analog 0 to 10 V) mean you can connect pushbuttons, limit switches, and up to four analog sensors — e.g., temperature or level transmitters — without an extra analog expansion module. The 4 transistor outputs sink 0.3 A each at 24 V DC, enough to drive small contactors, indicator lamps, or solenoid valves directly; for higher loads you add a relay interface. The 80-hour power reserve keeps the real-time clock and retentive data alive through a weekend power loss — critical for time-stamped event logging or scheduled start sequences. Ambient rating is 0 °C to 55 °C — fine for a ventilated electrical cabinet in a production hall, but not for a freezer or an unventilated roof-top enclosure. Approvals include UL, CSA, FM, and marine certification, so it passes inspection in North American panel shops, fire-pump controls, and shipboard installations without a separate component-level review.
DIN-rail footprint and expansion
Mounts on 35 mm DIN rail, occupies 4 spacing units (72 mm wide × 90 mm high × 55 mm deep). The LOGO! system is modularly expandable — you can add digital/analog I/O modules, communication modules (e.g., AS-Interface, KNX), or a display module to the right side via the built-in expansion bus.
