I/O budget and output drive limits
The 6ED1052-1CC00-0BA3 is the LOGO! 24 base unit with a backlit display, 8 digital inputs (of which 2 can be configured as 0-10 V analog inputs), and 4 transistor-sourced outputs rated 0.3 A per channel at 55 °C. That 0.3 A ceiling at the top of the operating range means each output drives a small contactor coil or indicator lamp directly — anything above that needs an interposing relay. The 24 V DC supply rail is shared across the module and its expansion bus. Memory is capped at 56 blocks for the function-block diagram or ladder program. That is enough for a pump sequencer, a small conveyor interlock, or a lighting schedule — not a multi-axis machine. The module is developed in accordance with IEC 61131 and carries CE, UL, CSA, FM, and marine approvals, so it qualifies for control cabinets on ships or in classified areas.
Panel fit and expansion
Depth is 55 mm, height 90 mm — it clears most shallow enclosures without a gland-plate conflict. The module is expandable with extra LOGO! I/O modules via the left-side bus connector, so a 4-DO base can grow to 16+ digital outputs if the application needs more. Rated for 0 to 55 °C ambient with no derating curve published in the spec — assume the 0.3 A per output holds across the band. The 24 V DC supply must be short-circuit protected; the module itself includes electrical short-circuit protection at 1 A on the output side.
