Siemens LOGO! 8.4 Grundgerät 24CEO – Compact PLC for Industrial Control
The Siemens LOGO! 8.4 24CEO is a compact PLC (Programmable Logic Controller) designed for small automation tasks in industrial and building technology applications. It provides a reliable, easy-to-program control solution for discrete logic tasks without the need for a separate display unit.
24 V DC supply voltage ensures compatibility with standard industrial DC power supplies
8 digital inputs allow connection of sensors, switches, and limit contacts for signal acquisition
4 digital outputs drive actuators, relays, and indicator lamps directly
As the base module of the LOGO! 8.4 series, this 24CEO variant delivers core logic processing capability in a minimal footprint. The absence of a built-in display keeps the unit compact and cost-effective, making it ideal for straightforward control loops that do not require on-device parameterisation.
Ideal für...
Small-scale automation in building technology, HVAC control, and light machinery where a full-scale PLC system would be oversized. Suitable for integrators and maintenance teams looking for a simple, reliable logic controller without complex programming environments.
Anwendung von Siemens LOGO! 8.4 24CEO
Used as a standalone controller for binary logic tasks such as pump switching, lighting control, and simple sequence control. Connect sensors to the 8 inputs, configure the logic via LOGO! Soft Comfort software on a PC, and deploy the program to the 4 outputs for direct actuator control.
