Industrial RGB Display
with Modbus TCP

LED_O is a compact round RGB LED display unit built for machine status, alarm indication, and industrial signage. Controlled by any PLC via Modbus TCP — or configured live from any browser via HTTPS.

Why LED_O?

Everything a PLC engineer or machine builder needs — out of the box, no middleware required.

Native Modbus TCP

FC03, FC06, and FC16 supported out of the box. Connect directly to any PLC on your network — no gateway, no driver, no middleware.

Built-in HTTPS Web Interface

Commission and configure from any browser. Change display content, set alarm thresholds, and update network settings without touching the PLC program.

Alarm Display with Colour Change

Set high and low alarm thresholds. LED_O automatically switches colour when limits are breached — a direct replacement for traditional stack lights.

UK Built, CE / UKCA Certified

Designed and built in Stoke-on-Trent. CE and UKCA marked. Direct support from the engineers who built it.
