In refineries and petrochemical plants, uninterrupted 24 V DC is vital for keeping PLCs, alarms, and safety shutdown systems online. The UNO-DIODE module allows two power supplies to work together while isolating them from each other. If one supply fails, the other immediately takes over without disturbing the load. This secure redundancy ensures that critical monitoring and safety functions continue running smoothly, reducing downtime risks and protecting expensive equipment in one of the most demanding industries.
Production lines with robotic arms, conveyors, and inspection systems depend on a constant power supply. Even a brief loss can halt production and lead to costly delays. By decoupling power supplies with diodes, the UNO-DIODE prevents a single supply fault from affecting the entire system. Its low voltage drop ensures stable output levels, keeping sensors, drives, and controllers operating without disruption. This design helps manufacturers maintain productivity, improve system resilience, and avoid unplanned shutdowns.
Public infrastructure such as water treatment, rail networks, or traffic management systems requires reliable power to keep essential services operating. The UNO-DIODE guarantees redundancy by linking two DC supplies while protecting connected loads from reverse currents and surges. This means that if one supply fails or is taken offline for maintenance, the second continues delivering uninterrupted power. As a result, critical systems stay online, ensuring public safety and service continuity even in harsh or unpredictable conditions.
Control panels in building automation, transportation, or small-scale machinery often have strict space limitations. The UNO-DIODE addresses this with its narrow 22.5 mm housing, which mounts directly onto a DIN rail. Despite its small size, it delivers high efficiency and supports up to 20 A, providing robust redundancy without consuming valuable enclosure space. This makes it a preferred choice for engineers who must balance compact design with reliable, fail-safe power distribution.
