How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Siemens LOGO! 8 6ED1052-2CC08-0BA2 (LOGO! 24CEo) is a modular logic module with 24 V DC supply, 8 digital inputs (4 configurable as 0-10 V analog), 4 transistor outputs, and capacity for 400 function blocks. It has no integrated display, includes an Ethernet interface with a web server and MQTT cloud connectivity, and mounts on a 35 mm DIN rail across 4 module widths.
The Ethernet/web-server/MQTT interface and cloud connectivity are what set this 24CEo variant apart from the non-Ethernet base version, useful when the controller needs to publish data to a cloud dashboard or be reached for remote diagnostics without an add-on communication module. With 4 of its 8 digital inputs usable as 0-10 V analog inputs, it covers simple sensor-feedback logic (level, pressure, speed) without a separate analog expansion module. Choose the display-equipped variant instead when local operator interaction without a PC or app is required.
Suited to simple machine control, HVAC sequencing, conveyor logic, and small automation cells that need cloud connectivity via MQTT or remote monitoring through the integrated web server.
