6ED1052-2FB08-0BA3, Siemens, LOGO! 230RCEo, 8 DI, 4 relay DO, without display

Siemens LOGO! 230RCEo – logic module without display, 8 DI and 4 relay outputs (6ED1052-2FB08-0BA3)

Siemens LOGO! 230RCEo is a compact programmable logic module of the LOGO! series 9 for everyday automation tasks. It offers 8 digital inputs for mains voltage, 4 relay outputs; max. 10 A resistive / 3 A inductive load and memory for up to 800 function blocks. Ethernet, integrated web server, data logging, user web pages, microSD, cloud connection and MQTT make local and remote management easier.

Key advantages
The version without display is suitable for closed switchboards; operation can be handled via the integrated web server or the external LOGO! TDE panel.
Eight digital inputs cover common signals from push buttons, switches, sensors and operating contacts.
Modular expansion allows additional digital, analogue or communication modules to be added according to the application.
Support for LOGO! Soft Comfort V9.0 or higher; older projects can still be run.
Operating temperature −20 to +55 °C and mounting on a standard 35 mm DIN rail.

Typical applications

The unit is suitable for mains-supplied switchboards, remote control of lighting, HVAC, pumps and simple process units. The compact design and network functions help with stand-alone machines and smaller process units without an unnecessarily complex PLC architecture.

Which assembly it belongs to

The basic module belongs to the Siemens LOGO! assembly 9. Complete it with compatible LOGO! expansion modules and LOGO! Soft Comfort software. Variant 230RCE or 230RCEo is supplied directly from 115/230 V AC/DC, so do not add a separate 24V power supply for the basic module.

Frequently asked questions
Is the unit suitable for LOGO! Soft Comfort V9?

Yes. This variant is designed for LOGO! Soft Comfort V9.0 or higher and also supports running older projects.

Can LOGO! be connected to Ethernet?

Yes. The basic module has Ethernet and supports an integrated web server, data logging, user web pages, cloud connection and MQTT.

When to choose this variant?

Choose it for 115/230V applications without the need for a built-in display; for local operation, LOGO! TDE can be added.
