Tight integrator note — 24 V DC logic block with display
The Siemens 6ED1052-1CC00-0BA4 is a LOGO! 24 logic module with a built-in display and keypad, running on 24 V DC. It gives you 8 digital inputs, two of which can read 0-10 V analog, and 4 transistor outputs rated at 0.3 A resistive. That output current handles small valves, indicators, or a contactor coil — but not a motor starter directly. Permissible supply range is 20.4 V to 28.8 V DC. Short-circuit protection is set at 1 A.
Relay-output sibling — 6ED1052-1MD00-0BA6
If you're comparing the 6ED1052-1CC00-0BA4 with the 6ED1052-1MD00-0BA6, the key difference is the output stage. The -1MD00 uses relay outputs rated 10 A resistive, with inductive load capability up to 3 A, and has no internal short-circuit protection — it expects external fusing. Its transistor counterpart here is limited to 0.3 A but includes self-protection.
Mounting and I/O detail
Slide onto 35 mm DIN rail at 4 spacing units; height is 90 mm. Supply range is 20.4 V to 28.8 V DC. Digital inputs: 8 total, with terminals 1-2 configurable as analog 0-10 V. Outputs: 4 transistor sinks, electrically protected to 1 A. Limit to 0.3 A resistive per channel; inductive loads need a flyback diode. The logic handles 130 blocks — enough for a small machine sequence or building automation controller.
