The 6AG1052-2MD08-7BA1: This is the SIPLUS variant of the LOGO! 8.3 — a 12/24 V DC logic module with conformal coating, rated for -40 to +70 °C ambient. It supplies 8 digital inputs (4 usable as analog 0-10 V) and 4 relay outputs (10 A resistive, 3 A inductive) with a 400-block memory and Ethernet for web server, data logging, and cloud connectivity. Cold restart is allowed down to -25 °C with condensation permitted, but no commissioning under condensation. The base unit is the standard 6ED1052-2MD08-0BA1; this version adds the extended temperature range and conformal coating for harsh environments.
How it sits against the standard LOGO! 8.3
The standard LOGO! 8.3 (6ED1052-2MD08-0BA1) lacks conformal coating. This SIPLUS version adds it with a -40 to +70 °C range, sharing the same footprint and I/O.
