Siemens 6ED1052-2MD08-0BA2 LOGO! 12/24RCEO 8DI/4DO 400 Blocks Logic Module

The Siemens 6ED1052-2MD08-0BA2 is a LOGO! 12/24RCEO logic module running on 12/24 V DC, with 8 digital inputs (4 usable as 0-10 V analog inputs) and 4 relay outputs switching up to 10 A resistive. It has no onboard display, stores up to 400 function blocks, and includes an integrated Ethernet port with web server and MQTT cloud connectivity.

Selection Notes

The RCEO suffix on this LOGO! variant means relay outputs, Ethernet, and no display - choose a module with a display built in if the panel needs local status/parameter viewing without a PC, or a transistor-output variant if outputs need to switch faster than relay contacts allow. Four of the eight digital inputs can be reconfigured as 0-10 V analog inputs, which covers simple process value monitoring (level, pressure, temperature transmitters) without adding a separate analog expansion module. The integrated web server and MQTT support let this module push status data to a local browser or a cloud broker without extra hardware.

Applications

Used as a standalone or networked small-machine controller for building services, pump/tank control, and simple process skids where a handful of relay outputs, analog inputs, and Ethernet-based monitoring cover the application without a full PLC.
