Meet LED-O.
We’re developing a family of LED displays in distinctive forms, starting with LED-O (LED-O): our round RGB display for machine status, alarm indication, and industrial signage. Designed and built by Midlands Electronic Solutions in Stoke-on-Trent, UK, it connects to any PLC via Modbus TCP and can be configured from a browser via HTTPS.
LED-O is not yet on sale. Contact us to discuss your application and future availability.
Why LED-O?
More information than a status light. Straightforward integration for PLC engineers and machine builders.
Built-in HTTPS Web Interface
Commission and configure from a browser — no dedicated software or app required. Set display content, alarm thresholds and network settings through the built-in HTTPS interface.
More Than a Warning Light
Show PLC-supplied alarm messages and numeric values, not just a coloured lamp. Set high and low thresholds for automatic colour changes, and use shapes or user-defined bitmaps for application-specific visual indications.
UK Built, CE / UKCA Preparation Underway
Designed and built in Stoke-on-Trent, with direct support from the engineers behind the hardware and firmware. CE/UKCA conformity assessment and technical documentation are in preparation; marking is not yet complete.
