Reliable Cellular Backhaul

Integrated industrial 4G LTE RTU engine with external SMA antenna port for uninterrupted data upload in low-signal areas.

Key features

Engineered for rapid field commissioning, the Reflex I/O bridges the gap between field sensors, heavy machinery, and cloud dashboards. Whether monitoring greenhouse microclimates, automating commercial HVAC & lighting, or tracking decentralized pumps and energy meters, this unit eliminates the overhead of sourcing separate DIN rail power supplies, enclosures, relays, and cellular gateways.

Inside its sealed housing, an integrated industrial 4G RTU pairs with dedicated terminal blocks and optional onboard power relays capable of direct switching up to 230VAC. With industrial-grade circular waterproof connectors and an integrated SMA external antenna, the Reflex I/O guarantees consistent connectivity and data integrity even in moist, dusty, or electrically noisy installations.
