What this module is and why it's worth the shelf space
The Siemens 6AG1052-2CC00-2BA6 is a SIPLUS LOGO! 24O digital I/O module designed for extended-temperature applications where standard LOGO! modules won't hold up. It's based on the 6ED1052-2CC00-0BA6 but with conformal coating and a -40 to +70°C range, making it a critical spare for panels in chillers, ovens, or outdoor cabinets. The conformal coating provides protection against humidity and mild chemical exposure, which is the main reason to pay the premium over the standard LOGO! variant.
Supply range 20.4-28.8 V DC. Digital inputs: 8 total, 4 can be configured as analog 0-10 V inputs. Digital outputs: 4 transistor outputs, each rated 0.3 A resistive with short-circuit protection at 1 A. Dimensions are compact: 72 mm wide, 90 mm tall, 55 mm deep. The wide ambient temperature span (-40 to +70°C) is the headline feature. At the high end, that covers many industrial ovens and solar-exposed enclosures; at the low end, cold storage or arctic installations.
