Phoenix Contact TRIO2-DIODE/12-24DC/2X20/1X40 ensures continuous power with diode redundancy, high efficiency, and reliable industrial performance.
The Phoenix Contact TRIO2-DIODE/12-24DC/2X20/1X40 redundancy module is built to secure reliable power delivery in demanding environments. It works by combining two power supply units in parallel while using diode technology for safe decoupling. This ensures that if one supply fails, the load continues to run without interruption. Supporting systems between 12 V and 24 V DC, it can deliver either 2 x 20 A or 1 x 40 A, making it suitable for both medium and heavy-duty loads. With a slim DIN-rail design, quick push-in wiring, and high efficiency, it simplifies installation while maximizing availability.
Engineered for critical applications, the TRIO2-DIODE redundancy module guarantees continuous operation by extending redundancy right up to the load. Its diode-based design prevents reverse currents, reducing system risks while keeping energy losses low. Efficiency above 97% ensures stable performance with minimal heat generation, while permanent monitoring maintains operational safety. The robust metal housing, wide ambient temperature tolerance, and protection against vibration make it ideal for tough industrial settings. By reducing downtime risks and safeguarding equipment, it delivers tangible benefits for automation systems, process lines, and mission-critical infrastructures.
Why TRIO2-DIODE/12-24DC/2X20/1X40?
Because it delivers uninterrupted reliability. The TRIO2-DIODE/12-24DC/2X20/1X40 ensures that even if one power supply fails, your system keeps running. It combines compact design, diode-based safety, and high efficiency into one solution that industries can trust for critical operations where downtime is not an option.
What problem does it solve?
It eliminates single-point failures in power supply systems. By decoupling parallel power supplies, the TRIO2-DIODE module prevents overloads, reverse currents, and unexpected shutdowns. This ensures maximum system availability and gives operators peace of mind in applications where continuous power is absolutely essential.

In oil refineries, continuous operation of control panels is vital since a single power interruption can halt production. Using a diode-based redundancy module allows two power supplies to run in parallel, with one acting as a backup. If the main unit fails, the second automatically takes over without any manual intervention. This seamless switching protects PLCs and critical controllers, ensuring refinery processes remain stable in harsh, high-demand environments.
Facilities like water treatment plants or railway signaling stations often operate in remote areas where maintenance access is limited. A redundancy module helps guarantee stable operation by decoupling power supplies, preventing system failures caused by overloads or faults. Its compact DIN-rail design fits into small control boxes, while its efficient operation reduces heat buildup, making it reliable for unattended, long-term installations.
Urban railways and metro networks depend on uninterrupted communication and signaling systems. A diode redundancy module protects these sensitive circuits by isolating power sources and preventing reverse current flow. Even in extreme temperature fluctuations or high-vibration environments, its robust construction ensures reliable operation. This prevents train delays, enhances passenger safety, and keeps transportation systems running smoothly with minimal downtime.
Automated production lines, especially in automotive and electronics sectors, cannot afford unexpected power losses. By integrating a redundancy module, factories can keep machines and robots powered continuously, even if one power supply drops out. The module ensures uninterrupted workflows, reduces costly stoppages, and allows maintenance to be carried out without shutting down the entire line. This boosts productivity and safeguards output quality.
